PHP Coding Standards
====================
This file lists several standards that any programmer, adding or changing
code in PHP, should follow. Since this file was added at a very late
stage of the development of PHP v3.0, the code base does not (yet) fully
follow it, but it's going in that general direction. Since we are now
well into the version 4 releases, many sections have been recoded to use
these rules.
Code Implementation
-------------------
[1] Functions that are given pointers to resources should not free them
For instance, function int mail(char *to, char *from) should NOT free
to and/or from.
Exceptions:
- The function's designated behavior is freeing that resource. E.g. efree()
- The function is given a boolean argument, that controls whether or not
the function may free its arguments (if true - the function must free its
arguments, if false - it must not)
- Low-level parser routines, that are tightly integrated with the token
cache and the bison code for minimum memory copying overhead.
[2] Functions that are tightly integrated with other functions within the
same module, and rely on each other non-trivial behavior, should be
documented as such and declared 'static'. They should be avoided if
possible.
[3] Use definitions and macros whenever possible, so that constants have
meaningful names and can be easily manipulated. The only exceptions
to this rule are 0 and 1, when used as false and true (respectively).
Any other use of a numeric constant to specify different behavior
or actions should be done through a #define.
[4] When writing functions that deal with strings, be sure to remember
that PHP holds the length property of each string, and that it
shouldn't be calculated with strlen(). Write your functions in a such
a way so that they'll take advantage of the length property, both
for efficiency and in order for them to be binary-safe.
Functions that change strings and obtain their new lengths while
doing so, should return that new length, so it doesn't have to be
recalculated with strlen() (e.g. php_addslashes())
[5] Use php_error() to report any errors/warnings during code execution.
Use descriptive error messages, and try to avoid using identical
error strings for different stages of an error. For example,
if in order to obtain a URL you have to parse the URL, connect,
and retreive the text, assuming something can go wrong at each
of these stages, don't report an error "Unable to get URL"
on all of them, but instead, write something like "Unable
to parse URL", "Unable to connect to URL server" and "Unable
to fetch URL text", respectively.
[6] NEVER USE strncat(). If you're absolutely sure you know what you're doing,
check its man page again, and only then, consider using it, and even then,
try avoiding it.
[7] Use ZEND_* macros instead of PHP_* macros. Use of PHP_* macros is not
recommended. Since most of the PHP_* macros are ZEND_* macro aliases, using
the PHP_* macros makes browsing the source code with a tag search harder.
[8] Use assert(). assert.h is included in php.h if it is available. Not only
does good assertion catch bugs, but it also helps with code readability.
- Do not use assert for error handling. Use assert only for the
condition that must be always true.
- Do not use assignments in assert conditions. If you assign inside an
assert condition, you risk an elusive bug that would be very difficult
to spot in a debug build, due to the side effect of the assignment.
Function calls in assert conditions may also cause this problem, if
they modify one of their arguments or global variables.
Naming Conventions
------------------
[1] Function names for user-level functions should be enclosed with in
the PHP_FUNCTION() macro. They should be in lowercase, with words
underscore delimited, with care taken to minimize the letter count.
Abbreviations should not be used when they greatly decrease the
readability of the function name itself.
Good:
'mcrypt_enc_self_test'
'mysql_list_fields'
Ok:
'mcrypt_module_get_algo_supported_key_sizes'
(could be 'mcrypt_mod_get_algo_sup_key_sizes'?)
'get_html_translation_table'
(could be 'html_get_trans_table'?)
Bad:
'hw_GetObjectByQueryCollObj'
'pg_setclientencoding'
'jf_n_s_i'
[2] If they are part of a "parent set" of functions, that parent should
be included in the user function name, and should be clearly related
to the parent program or function family. This should be in the form
of parent_*.
A family of 'foo' functions, for example:
Good:
'foo_select_bar'
'foo_insert_baz'
'foo_delete_baz'
Bad:
'fooselect_bar'
'fooinsertbaz'
'delete_foo_baz'
[3] Function names used by user functions should be prefixed
with "_php_", and followed by a word or an underscore-delimited list of
words, in lowercase letters, that describes the function. If applicable,
they should be declared 'static'.
[4] Variable names must be meaningful. One letter variable names must be
avoided, except for places where the variable has no real meaning or
a trivial meaning (e.g. for (i=0; i<100; i++) ...).
[5] Variable names should be in lowercase. Use underscores to separate
between words.
Syntax and indentation
----------------------
[1] Never use C++ style comments (i.e. // comment). Always use C-style
comments instead. PHP is written in C, and is aimed at compiling
under any ANSI-C compliant compiler. Even though many compilers
accept C++-style comments in C code, you have to ensure that your
code would compile with other compilers as well.
The only exception to this rule is code that is Win32-specific,
because the Win32 port is MS-Visual C++ specific, and this compiler
is known to accept C++-style comments in C code.
[2] Use K&R-style. Of course, we can't and don't want to
force anybody to use a style he or she is not used to, but,
at the very least, when you write code that goes into the core
of PHP or one of its standard modules, please maintain the K&R
style. This applies to just about everything, starting with
indentation and comment styles and up to function declaration
syntax.
(see also http://www.tuxedo.org/~esr/jargon/html/entry/indent-style.html)
[3] Be generous with whitespace and braces. Always prefer:
if (foo) {
bar;
}
to:
if(foo)bar;
Keep one empty line between the variable declaration section and
the statements in a block, as well as between logical statement
groups in a block. Maintain at least one empty line between
two functions, preferably two.
[4] When indenting, use the tab character. A tab is expected to represent
four spaces. It is important to maintain consistency in indenture so
that definitions, comments, and control structures line up correctly.
Documentation and Folding Hooks
-------------------------------
In order to make sure that the online documentation stays in line with
the code, each user-level function should have its user-level function
prototype before it along with a brief one-line description of what the
function does. It would look like this:
/* {{{ proto int abs(int number)
Returns the absolute value of the number */
PHP_FUNCTION(abs)
{
...
}
/* }}} */
The {{{ symbols are the default folding symbols for the folding mode in
Emacs and vim (set fdm=marker). Folding is very useful when dealing with
large files because you can scroll through the file quickly and just unfold
the function you wish to work on. The }}} at the end of each function marks
the end of the fold, and should be on a separate line.
The "proto" keyword there is just a helper for the doc/genfuncsummary script
which generates a full function summary. Having this keyword in front of the
function prototypes allows us to put folds elsewhere in the code without
messing up the function summary.
Optional arguments are written like this:
/* {{{ proto object imap_header(int stream_id, int msg_no [, int from_length [, int subject_length [, string default_host]]])
Returns a header object with the defined parameters */
And yes, please keep the prototype on a single line, even if that line
is massive.
New and Experimental Functions
-----------------------------------
To reduce the problems normally associated with the first public
implementation of a new set of functions, it has been suggested
that the first implementation include a file labeled 'EXPERIMENTAL'
in the function directory, and that the functions follow the
standard prefixing conventions during their initial implementation.
The file labelled 'EXPERIMENTAL' should include the following
information:
Any authoring information (known bugs, future directions of the module).
Ongoing status notes which may not be appropriate for CVS comments.
Aliases & Legacy Documentation
-----------------------------------
You may also have some deprecated aliases with close to duplicate
names, for example, somedb_select_result and somedb_selectresult. For
documentation purposes, these will only be documented by the most
current name, with the aliases listed in the documentation for
the parent function. For ease of reference, user-functions with
completely different names, that alias to the same function (such as
highlight_file and show_source), will be separately documented. The
proto should still be included, describing which function is aliased.
Backwards compatible functions and names should be maintained as long
as the code can be reasonably be kept as part of the codebase. See
/phpdoc/README for more information on documentation.

Installation Instructions for PHP 4
-----------------------------------
STOP!
Before going any further, please remember you are going to find more
up to date instructions in the online manual, located here:
http://www.php.net/manual/en/install.apache.php
It is strongly recommended that you read the manual page before going
further. However, for the impatient, here is a quick set of steps that
will build PHP as (first) a dynamic Apache module (DSO) for Apache 1.3.x
with MySQL support and then a static module. A more verbose explanation follows.
For installing PHP on other web servers, refer to one of the following
files:
sapi/aolserver/README
sapi/pi3web/README
sapi/servlet/README
sapi/thttpd/README
README.Zeus
Some notes:
1: Only install either the static module or the dynamic one. Do not
install both.
2: If you are recompiling PHP to add new extensions or upgrading
something like GD, remove the config.cache file before you re-run
configure.
3: If you are on Linux and have installed shared libraries, make
sure the location of these shared libraries are listed in your
/etc/ld.so.conf file. For example, if you have:
/usr/local/lib/mysql/libmysqlclient.so
Make sure /etc/ld.so.conf contains:
/usr/local/lib/mysql
Then run ldconfig.
If you want both PHP 3 and 4 modules in the same Apache server, check the
bottom of this file for instructions.
INSTALLATION WITH THE ZEUS WEB SERVER:
--Please see the 'README.Zeus' file included in this distribution
QUICK INSTALL (DSO)
For this to work your Apache httpd must have mod_so enabled.
Check using httpd -l. You should see something like:
Compiled-in modules:
http_core.c
mod_so.c
Chances are you will see a lot more modules than these two. That's ok,
as long as mod_so.c shows up you can proceed with the following steps:
$ gunzip -c php-4.x.y.tar.gz | tar xf -
$ cd php-4.x.y
$ ./configure --with-mysql --with-apxs
$ make
$ make install
If you get an error telling you that the apxs script could not be found,
look for it on your system and if you find it, provide the full path to it
as: --with-apxs=/path/to/apxs
Next you must copy php.ini-dist to the appropriate place (normally
/usr/local/lib/php.ini) and edit it as necessary to set PHP options.
The only thing left to do is to edit your httpd.conf file and make sure the
PHP 4 mime type is there and uncommented. You need a line that looks like
this:
AddType application/x-httpd-php .php
Then restart your server (apachectl restart) and you should be able to
serve up PHP files now. Make a test file called test.php and put some
PHP tags in it. Like <?phpinfo()?>, for example.
QUICK INSTALL (Static)
$ gunzip -c apache_1.3.x.tar.gz | tar xf -
$ cd apache_1.3.x
$ ./configure
$ cd ..
$ gunzip -c php-4.x.y.tar.gz | tar xf -
$ cd php-4.x.y
$ ./configure --with-mysql --with-apache=../apache_1.3.x
$ make
$ make install
$ cd ../apache_1.3.x
$ ./configure --prefix=/www --activate-module=src/modules/php4/libphp4.a
(The above line is correct! Yes, we know libphp4.a does not exist at this
stage. It isn't supposed to. It will be created.)
$ make
(you should now have an httpd binary which you can copy to your Apache bin dir if
is is your first install then you need to "make install" as well)
$ cd ../php-4.x.y
$ cp php.ini-dist /usr/local/lib/php.ini
You can edit /usr/local/lib/php.ini file to set PHP options.
Edit your httpd.conf or srm.conf file and add:
AddType application/x-httpd-php .php
VERBOSE INSTALL
Chances are you are reading this because the quick install steps above
did not work for you. If this is the case, congratulations, you are
among the elite few that actually reads documentation. It really is
not a difficult install and once you have done it once you will fly
through it.
Installing PHP can be done in four simple steps:
1. Unpack your distribution file.
You will have downloaded a file named something like php-4.x.y.tar.gz.
Unzip this file with a command like: gunzip php-4.x.y.tar.gz
Next you have to untar it with: tar -xvf php-4.x.y.tar
This will create a php-4.x.y directory. cd into this new directory.
2a. Configure PHP (Dynamic Module) - Skip to 2b if you wish to build
a static module
You now have to choose the options you would like. There are quite
a few of them. To see a list, type: ./configure --help
The only options that you are likely to want to use are the ones in
the last section entitled, "--enable and --with options recognized:"
A popular choice is to build the Apache module version. In order to
build PHP as a dynamic module for Apache-1.3.x you have to first have
Apache installed. Assuming Apache is already installed, make sure
the shared object module is enabled. To check this, type: httpd -l
You should see something like:
Compiled-in modules:
http_core.c
mod_so.c
You will most likely have a lot more modules than what is shown here.
As long as mod_so.c shows up in the list, PHP should be happy.
Now, type: ./configure --with-mysql --with-apxs
If you get an error telling you that the apxs script could not be found,
look for it on your system and if you find it, provide the full path to it
as: --with-apxs=/path/to/apxs
You might also want other flags on this configure line. --with-mysql
is just an example.
There are a few things that can go wrong during this configure step.
The most common is that you have asked for an option and that the
configure script can not find the files required to enable this
option in PHP. Chances are you can provide the full path to the
base directory under which the related files were installed. For
example, if you have installed the GD library in /opt/gd which means
that /opt/gd/include has your GD header files and /opt/gd/lib contains
your GD library files, you would use --with-gd=/opt/gd
Skip to step 3 for compilation and installation instructions.
2b. Configure PHP (Static Module) - Skip if you performed 2a
You now have to choose the options you would like. There are quite
a few of them. To see a list, type: ./configure --help
The only options that you are likely to want to use are the ones in
the last section entitled, "--enable and --with options recognized:"
A popular choice is to build the Apache module version. You need
to know where the source code directory for your Apache server is
located. Then use an option like: --with-apache=/usr/local/src/apache
if that is your Apache source code directory. If you only specify
--with-apache, then it will default to look for your Apache source
in /usr/local/etc/httpd.
NOTE: The directory you specify should be the top-level of the
unpacked Apache (or Stronghold) distribution. The configure program
will automatically look for httpd.h in different directories under that
location depending on which version of Apache, including Stronghold,
you are running.
For MySQL support, since newer versions of MySQL installs its various
components under /usr/local, this is the default. If you have
changed the location you can specify it with: --with-mysql=/opt/local
for example. Otherwise just use: --with-mysql
*NOTE* If you are using Apache 1.3b6 or later, you should run the
Apache Configure script at least once before compiling PHP. It
doesn't matter how you have Apache configured at this point.
Skip to step 3b at this point.
3. Compile and install the files. Simply type: make install
3a. Dynamic Module Installation
Nothing else is needed here. Proceed to step 4a.
3b. Static Module Installation
For the Apache module version this will copy the appropriate files
to the src/modules/php4 directory in your Apache distribution if
you are using Apache 1.3.x. If you are still running Apache 1.2.x
these files will be copied directly to the main src directory.
For Apache 1.3b6 and later, you can use the new APACI configuration
mechanism. To automatically build Apache with PHP support, use:
cd apache_1.3.x
./configure --prefix=/<path>/apache \
--activate-module=src/modules/php4/libphp4.a
make
make install
If you do not wish to use this new configuration tool, the old
install procedure (src/Configure) will work fine.
If you are using the old Apache ./Configure script, you will have to
edit the Apache src/Configuration file manually. If you do not have
this file, copy Configuration.tmpl to Configuration.
For Apache 1.3.x add:
AddModule modules/php4/libphp4.a
For Apache 1.3.x don't do anything else. Just add this line and then
run "./Configure" followed by "make".
For Apache 1.2.x add:
Module php4_module mod_php4.o
For Apache 1.2.x you will also have to look in the libphp4.module file,
which was copied to the src directory. The EXTRA_LIBS line in the Apache
Configuration file needs to be set to use the same libs as specified on
the LIBS line in libphp4.module. You also need to make sure to add
"-L." to the beginning of the EXTRA_LIBS line.
So, as an example, your EXTRA_LIBS line might look like:
EXTRA_LIBS=-L. -lphp4 -lgdbm -ldb -L/usr/local/mysql/lib -lmysqlclient
NOTE: You should not enclose the EXTRA_LIBS line in double-quotes, as it
is in the libphp4.module file.
Also, look at the RULE_WANTHSREGEX setting in the libphp4.module file
and set the WANTHSREGEX directive accordingly in your Configuration file.
This last step applies to versions of Apache prior to 1.3b3.
This is a bit of a hassle, but should serve as incentive to move to
Apache 1.3.x where this step has been eliminated.
Once you are satisfied with your Configuration settings, type: ./Configure
If you get errors, chances are that you forgot a library or made a typo
somewhere. Re-edit Configuration and try again. If it goes well,
type: make
Assuming it compiles without errors, proceed to step 4b.
4a. Setting up the server. (Dynamic Module)
The make install command in step 3 should have done most of your
work for you. It actually edits your httpd.conf file and tries to
enable the dynamic PHP module. To verify this, look for a line that
looks like this:
LoadModule php4_module libexec/libphp4.so
The actual path before the libphp4.so part might differ slightly. This
is likely fine. If you are paranoid you can examine the output from the
make install step to see where the libphp4.so file was actually put and
place the full path to this file on this LoadModule line.
If somewhere in your httpd.conf file you have a ClearModuleList line
then you also need this line:
AddModule mod_php4.c
And finally you need to tell Apache which file extension should trigger
PHP. You do this by creating a special mime type and associating it
with an extension. We suggest using:
AddType application/x-httpd-php .php
You are however free to use any extension you wish, including .html.
Note! If a line has a # at the beginning, then it is commented out
and you need to remove the # for that line to take effect.
Finally you need to copy php.ini-dist to the appropriate place
(normally /usr/local/lib/php.ini) and edit if necessary.
Once you have made these changes you should be ready to restart your
server and try it out. Type: apachectl restart
4b. Setting up the server. (Static Module)
You should now have a new httpd binary. Shut down your existing server,
if you have one, and copy this new binary overtop of it. Perhaps make
a backup of your previous one first. Then edit your conf/httpd.conf file
and add the line:
AddType application/x-httpd-php .php
There is also an interesting feature which can be quite instructive and
helpful while debugging. That is the option of having colour syntax
highlighting. To enable this, add the following line:
AddType application/x-httpd-php-source .phps
Any file ending in .phps will now be displayed with full colour syntax
highlighting instead of being executed.
Note that on some older server setups, the AddType lines are in the
conf/srm.conf file instead of conf/httpd.conf.
Note! If a line has a # at the beginning, then it is commented out
and you need to remove the # for that line to take effect.
When you are finished making changes to your httpd.conf file, you need
to copy php.ini-dist to the appropriate place (normally
/usr/local/lib/php.ini) and edit if necessary. You can then
start up your server.
5. Testing it all worked
Create a test file named test.php in your web tree somewhere and
put some test PHP tags in it. <?phpinfo()?> is a good first test.
This tag tells PHP to do a braindump and tells you all sorts of things
about itself.

Correct.

Correct, depending on the meaning of "relocatable". PIC code typically
does not contain relocations; that's why its position-independent.

Correct. However, a non-trivial shared library typically won't be
position-independent unless explicitly compiled with
-fPIC. Linux/glibc indeed does not require a shared library to be
position-independent; instead, it will perform the relocations in the
binary, even if they refer to code pages. As a result, those relocated
pages won't be shared across processes, anymore.

Martin
USING PHP 3 AND PHP 4 AS CONCURRENT APACHE MODULES
With some (newer) installations of Apache, it's possible to compile both
PHP 3 and PHP 4, and run them concurrently.
Note, it's only really wise to do this if you need to use the PHP 3 engine
to maintain backwards compatibility.
To enable it, configure PHP 3 and PHP 4 to use APXS (--with-apxs) and the
necessary link extensions (--enable-versioning). Otherwise, all standard
installations instructions apply. For example:
$ ./configure \
--with-apxs=/apache/bin/apxs \
--enable-versioning \
--with-mysql \

This is the first file you should be reading after you get your CVS account.
We'll assume you're basically familiar with CVS, but feel free to post
your questions on the mailing list. Please have a look at
http://cvsbook.red-bean.com/ for more detailed information on CVS.
PHP is developed through the efforts of a large number of people.
Collaboration is a Good Thing(tm), and CVS lets us do this. Thus, following
some basic rules with regards to CVS usage will:
a. Make everybody happier, especially those responsible for maintaining
the CVS itself.
b. Keep the changes consistently well documented and easily trackable.
c. Prevent some of those 'Oops' moments.
d. Increase the general level of good will on planet Earth.
Having said that, here are the organizational rules:
1. Respect other people working on the project.
2. Discuss any significant changes on the list before committing.
3. Look at EXTENSIONS file to see who is the primary maintainer of
the code you want to contribute to.
4. If you "strongly disagree" about something another person did, don't
start fighting publicly - take it up in private email.
5. If you don't know how to do something, ask first!
6. Test your changes before committing them. We mean it. Really.
The next few rules are more of a technical nature.
1. DO NOT TOUCH ChangeLog! It is automagically updated from the commit
messages every day. Woe be to those who attempt to mess with it.
2. All news updates intended for public viewing, such as new features,
bug fixes, improvements, etc., should go into the NEWS file. Also see
the note below about automatically updating NEWS in your commit message.
3. Do not commit multiple file and dump all messages in one commit. If you
modified several unrelated files, commit each group separately and
provide a nice commit message for each one. See example below.
4. Do write your commit message in such a way that it makes sense even
without the corresponding diff. One should be able to look at it, and
immediately know what was modified. Definitely include the function name
in the message as shown below.
5. In your commit messages, keep each line shorter than 80 characters. And
try to align your lines vertically, if they wrap. It looks bad otherwise.
6. If you modified a function that is callable from PHP, prepend PHP to
the function name as shown below.
The format of the commit messages is pretty simple.
If a line begins with #, it is taken to be a comment and will not appear
in the ChangeLog. If the line begins with @, it will be redirected to the
NEWS file. Everything else goes into the ChangeLog.
It is important to note that if your comment or news logline spans multiple
lines, you have to put # or @ at the beginning of _every_ such line. Every
entry in NEWS has to have a name after it, so if you did it with someone's
help, put both your names there. Your name WILL NOT be automatically put
at the end of the NEWS entry - so, please provide it yourself.
Example. Say you modified two files, datetime.c and string.c. In datetime.c
you added a new format option for date() function, and in string.c you fixed
a memory leak in php_trim(). Don't commit both of these at once. Commit them
separately and try to make sure your commit messages look something like the
following.
For datetime.c:
(PHP date) Added new 'K' format modifier for printing out number of
days until New Year's Eve.
@- Added new 'K' format modifier that will output the number of days
@ until New Year's Eve. (Bob)
For string.c:
(php_trim) Fixed a memory leak resulting from improper use of zval_dtor().
# Man, that thing was leaking all over the place!
@- Memory leak in trim() function has finally been fixed. (Bob)
The lines above marked with @ will go into NEWS file automagically, and the
# lines will be omitted from the ChangeLog. Alternatively, you might want
to modify NEWS file directly and not use the @ lines.
If you fix some bugs, you should note the bug ID numbers in your
commit message. Bug ID should be prefixed by "#" for easier access to
bug report when developers are browsing CVS via. LXR or Bonsai.
Example:
Fixed pgsql notice handler double free crash bug. Bug #14016
@ Fixed pgsql notice handler double free crash bug. Bug #14016
If you don't see your messages in ChangeLog and NEWS right away, don't worry!
These files are updated once a day, so your stuff will not show up until
somewhat later. Don't go adding stuff to NEWS by hand if you already put @
lines in the commit message.
You can use LXR (http://lxr.php.net/) and Bonsai (http://bonsai.php.net/)
to look at PHP CVS repository in various ways.
To receive daily updates to ChangeLog and NEWS, send an empty message to
php-cvs-daily-subscribe@lists.php.net.
Happy hacking,

Between PHP 4.0.6 and 4.1.0, the Zend module struct changed in a way
that broke both source and binary compatibility. If you are
maintaining a third party extension, here's how to update it:
If this was your old module entry:
zend_module_entry foo_module_entry = {
"foo", /* extension name */
foo_functions, /* extension function list */
NULL, /* extension-wide startup function */
NULL, /* extension-wide shutdown function */
PHP_RINIT(foo), /* per-request startup function */
PHP_RSHUTDOWN(foo), /* per-request shutdown function */
PHP_MINFO(foo), /* information function */
STANDARD_MODULE_PROPERTIES
};
Here's how it should look if you want your code to build with PHP
4.1.0 and up:
zend_module_entry foo_module_entry = {
#if ZEND_MODULE_API_NO >= 20010901
STANDARD_MODULE_HEADER,
#endif
"foo", /* extension name */
foo_functions, /* extension function list */
NULL, /* extension-wide startup function */
NULL, /* extension-wide shutdown function */
PHP_RINIT(foo), /* per-request startup function */

PHP_MINFO(foo), /* information function */
#if ZEND_MODULE_API_NO >= 20010901
FOO_VERSION, /* extension version number (string) */
#endif
STANDARD_MODULE_PROPERTIES
};
If you don't care about source compatibility with earlier PHP releases
than 4.1.0, you can drop the #if/#endif lines.

WHAT IT IS
It's a tool for automatically creating the basic framework for a PHP module
and writing C code handling arguments passed to your functions from a simple
configuration file. See an example at the end of this file.
HOW TO USE IT
Very simple. First, cd do directory ext/ in PHP 4 sources. If you just need
the basic framework and will be writing all the code in your functions
yourself, you can now do
./ext_skel --extname=module_name
and everything you need is placed in directory module_name.
[ Note that GNU awk is likely required for this script to work. Debian
systems seem to default to using mawk, so you may need to change the
#! line in skeleton/create_stubs to use gawk explicitly. ]
If you don't need to test the existence of any external header files,
libraries or functions in them, the module is already almost ready to be
compiled in PHP. Just remove 3 comments in your_module_name/config.m4,
cd back up to PHP sources top directory, and do
./buildconf; ./configure --enable-module_name; make
But if you already have planned the overall scheme of your module, what
functions it will contain, their return types and the arguments they take
(a very good idea) and don't want to bother yourself with creating function
definitions and handling arguments passed yourself, it's time to create a
function definitions file, which you will give as an argument to ext_skel
with option
--proto=filename.
FORMAT OF FUNCTION DEFINITIONS FILE
All the definitions must be on one line. In it's simplest form, it's just
the function name, ie.
my_function
but then you'll be left with an almost empty function body without any
argument handling.
Arguments are given in parenthesis after the function name, and are of
the form 'argument_type argument_name'. Arguments are separated from each
other with a comma and optional space. Argument_type can be one of int,
bool, double, float, string, array, object or mixed.
An optional argument is separated from the previous by an optional space,
then '[' and of course comma and optional space, like all the other
arguments. You should close a row of optional arguments with same amount of
']'s as there where '['s. Currently, it does not harm if you forget to do it
or there is a wrong amount of ']'s, but this may change in the future.
An additional short description may be added after the parameters.
If present it will be filled into the 'proto' header comments in the stubs
code and the <refpurpose> tag in the XML documentation.
An example:
my_function(int arg1, int arg2 [, int arg3 [, int arg4]]) this is my 1st
Arguments arg3 and arg4 are optional.
If possible, the function definition should also contain it's return type
in front of the definition. It's not actually used for any C code generating
purposes but PHP in-source documentation instead, and as such, very useful.
It can be any of int, double, string, bool, array, object, resource, mixed
or void.
The file must contain nothing else but function definitions, no comments or
empty lines.
OTHER OPTIONS
--no-help
By default, ext_skel creates both comments in the source code and a test
function to help first time module writers to get started and testing
configuring and compiling their module. This option turns off all such things
which may just annoy experienced PHP module coders. Especially useful with
--stubs=file
which will leave out also all module specific stuff and write just function
stubs with function value declarations and passed argument handling, and
function entries and definitions at the end of the file, for copying and
pasting into an already existing module.
--assign-params
--string-lens
By default, function proto 'void foo(string bar)' creates the following:
...
zval **bar;
... (zend_get_parameters_ex() called in the middle...)
convert_to_string_ex(bar);
Specifying both of these options changes the generated code to:
...
zval **bar_arg;
int bar_len;
char *bar = NULL;
... (zend_get_parameters_ex() called in the middle...)
convert_to_string_ex(bar_arg);
bar = Z_STRVAL_PP(bar_arg);
bar_len = Z_STRLEN_PP(bar_arg);
You shouldn't have to ask what happens if you leave --string-lens out. If you
have to, it's questionable whether you should be reading this document.
--with-xml[=file]
Creates the basics for phpdoc .xml file.
--full-xml
Not implemented yet. When or if there will ever be created a framework for
self-contained extensions to use phpdoc system for their documentation, this
option enables it on the created xml file.
CURRENT LIMITATIONS, BUGS AND OTHER ODDITIES
Only arguments of types int, bool, double, float, string and array are
handled. For other types you must write the code yourself. And for type
mixed, it wouldn't even be possible to write anything, because only you
know what to expect.
It can't handle correctly, and probably never will, variable list of
of arguments. (void foo(int bar [, ...])
Don't trust the generated code too much. It tries to be useful in most of
the situations you might encounter, but automatic code generation will never
beat a programmer who knows the real situation at hand. ext_skel is generally
best suited for quickly generating a wrapper for c-library functions you
might want to have available in PHP too.
This program doesn't have a --help option. It has --no-help instead.
EXAMPLE
The following _one_ line
bool my_drawtext(resource image, string text, resource font, int x, int y [, int color])
will create this function definition for you (note that there are a few
question marks to be replaced by you, and you must of course add your own
value definitions too):
/* {{{ proto bool my_drawtext(resource image, string text, resource font, int x, int y[, int color])
*/

New parameter parsing functions
===============================
It should be easier to parse input parameters to an extension function.
Hence, borrowing from Python's example, there are now a set of functions
that given the string of type specifiers, can parse the input parameters
and store the results in the user specified variables. This avoids most
of the IS_* checks and convert_to_* conversions. The functions also
check for the appropriate number of parameters, and try to output
meaningful error messages.
Prototypes
----------
/* Implemented. */
int zend_parse_parameters(int num_args TSRMLS_DC, char *type_spec, ...);
int zend_parse_parameters_ex(int flags, int num_args TSRMLS_DC, char *type_spec, ...);
The zend_parse_parameters() function takes the number of parameters
passed to the extension function, the type specifier string, and the
list of pointers to variables to store the results in. The _ex() version
also takes 'flags' argument -- current only ZEND_PARSE_PARAMS_QUIET can
be used as 'flags' to specify that the function should operate quietly
and not output any error messages.
Both functions return SUCCESS or FAILURE depending on the result.
The auto-conversions are performed as necessary. Arrays, objects, and
resources cannot be autoconverted.
Type specifiers
---------------
l - long
d - double
s - string (with possible null bytes) and its length
b - boolean, stored in zend_bool
r - resource (stored in zval)
a - array
o - object (of any type)
O - object (of specific type, specified by class entry)
z - the actual zval
The following characters also have a meaning in the specifier string:
| - indicates that the remaining parameters are optional, they
should be initialized to default values by the extension since they
will not be touched by the parsing function if they are not
passed to it.
/ - use SEPARATE_ZVAL_IF_NOT_REF() on the parameter it follows
! - the parameter it follows can be of specified type or NULL (only applies
to 'a', 'o', 'O', 'r', and 'z'). If NULL is passed, the results
pointer is set to NULL as well.
Examples
--------
/* Gets a long, a string and its length, and a zval */
long l;
char *s;
int s_len;
zval *param;
if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "lsz",
&l, &s, &s_len, &param) == FAILURE) {
return;
}
/* Gets an object of class specified by my_ce, and an optional double. */
zval *obj;
double d = 0.5;
zend_class_entry my_ce;
if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "O|d",
&obj, my_ce, &d) == FAILURE) {
return;
}
/* Gets an object or null, and an array.
If null is passed for object, obj will be set to NULL. */
zval *obj;
zval *arr;
if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "o!a",
&obj, &arr) == FAILURE) {
return;
}
/* Gets a separated array which can also be null. */
zval *arr;
if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "a/!",
&arr) == FAILURE) {
return;
}
/* Get only the first three parameters (useful for varargs functions). */
zval *z;
zend_bool b;
zval *r;
if (zend_parse_parameters(3 TSRMLS_CC, "zbr!",
&z, &b, &r) == FAILURE) {
return;
}
/* Get either a set of 3 longs or a string. */
long l1, l2, l3;
char *s;
if (zend_parse_parameters_ex(ZEND_PARSE_PARAMS_QUIET, ZEND_NUM_ARGS() TSRMLS_CC,
"lll", &l1, &l2, &l3) == SUCCESS) {

QNX4 Installation Notes
-----------------------
NOTE: General installation instructions are in the INSTALL file
1. To compile and test PHP3 you have to grab, compile and install:
- GNU dbm library or another db library;
- GNU bison (1.25 or later; 1.25 tested);
- GNU flex (any version supporting -o and -P options; 2.5.4 tested);
- GNU diffutils (any version supporting -w option; 2.7 tested);
2. To use CVS version you may need also:
- GNU CVS (1.9 tested);
- GNU autoconf (2.12 tested);
- GNU m4 (1.3 or later preferable; 1.4 tested);
3. To run configure define -lunix in command line:
LDFLAGS=-lunix ./configure
4. To use Sybase SQL Anywhere define ODBC_QNX and CUSTOM_ODBC_LIBS in
command line and run configure with --with-custom-odbc:
CFLAGS=-DODBC_QNX LDFLAGS=-lunix CUSTOM_ODBC_LIBS="-ldblib -lodbc" ./configure --with-custom-odbc=/usr/lib/sqlany50
If you have SQL Anywhere version 5.5.00, then you have to add
CFLAGS=-DSQLANY_BUG
to workaround its SQLFreeEnv() bug. Other versions has not been tested,
so try without this flag first.
5. To build the Apache module, you may have to hardcode an include path for
alloc.h in your Apache base directory:
- APACHE_DIRECTORY/src/httpd.h:
change #include "alloc.h"
to #include "APACHE_DIRECTORY/src/alloc.h"
Unless you want to use system regex library, you have to hardcode also
a path to regex.h:
- APACHE_DIRECTORY/src/conf.h:
change #include <regex.h>
to #include "APACHE_DIRECTORY/src/regex/regex.h"
I don't know so far why this required for QNX, may be it is Watcom
compiler problem.
If you building Apache module with SQL Anywhere support, you'll get
symbol conflict with BOOL. It is defined in Apache (httpd.h) and in
SQL Anywhere (odbc.h). This has nothing to do with PHP, so you have to
fix it yourself someway.
6. With above precautions, it should compile as is and pass regression
tests completely:
make
make check
make install
Don't bother me unless you really sure you made that all but it
still doesn't work.

=============================================================================
HOW TO CREATE A SELF-CONTAINED PHP EXTENSION
A self-contained extension can be distributed independently of
the PHP source. To create such an extension, three things are
required:
- Configuration file (config.m4)
- Source code for your module
We will describe now how to create these and how to put things
together.
PREPARING YOUR SYSTEM
While the result will run on any system, a developer's setup needs these
tools:
GNU autoconf
GNU automake
GNU libtool
GNU m4
All of these are available from
ftp://ftp.gnu.org/pub/gnu/
CONVERTING AN EXISTING EXTENSION
Just to show you how easy it is to create a self-contained
extension, we will convert an embedded extension into a
self-contained one. Install PHP and execute the following
commands.
$ mkdir /tmp/newext
$ cd /tmp/newext
You now have an empty directory. We will copy the files from
the mysql extension:
$ cp -rp php-4.0.X/ext/mysql/* .
It is time to finish the module. Run:
$ phpize
You can now ship the contents of the directory - the extension
can live completely on its own.
The user instructions boil down to
$ ./configure \
[--with-php-config=/path/to/php-config] \
[--with-mysql=MYSQL-DIR]
$ make install
The MySQL module will either use the embedded MySQL client
library or the MySQL installation in MYSQL-DIR.
DEFINING THE NEW EXTENSION
Our demo extension is called "foobar".
It consists of two source files "foo.c" and "bar.c"
(and any arbitrary amount of header files, but that is not
important here).
The demo extension does not reference any external
libraries (that is important, because the user does not
need to specify anything).
LTLIBRARY_SOURCES specifies the names of the sources files. You can
name an arbitrary number of source files here.
CREATING THE M4 CONFIGURATION FILE
The m4 configuration can perform additional checks. For a
self-contained extension, you do not need more than a few
macro calls.
------------------------------------------------------------------------------
PHP_ARG_ENABLE(foobar,whether to enable foobar,
[ --enable-foobar Enable foobar])
if test "$PHP_FOOBAR" != "no"; then
PHP_NEW_EXTENSION(foobar, foo.c bar.c, $ext_shared)
fi
------------------------------------------------------------------------------
PHP_ARG_ENABLE will automatically set the correct variables, so
that the extension will be enabled by PHP_NEW_EXTENSION in shared mode.
The first argument of PHP_NEW_EXTENSION describes the name of the
extension. The second names the source-code files. The third passes
$ext_shared which is set by PHP_ARG_ENABLE/WITH to PHP_NEW_EXTENSION.
Please use always PHP_ARG_ENABLE or PHP_ARG_WITH. Even if you do not
plan to distribute your module with PHP, these facilities allow you
to integrate your module easily into the main PHP module framework.
CREATING SOURCE FILES
ext_skel can be of great help when creating the common code for all modules
in PHP for you and also writing basic function definitions and C code for
handling arguments passed to your functions. See README.EXT_SKEL for further
information.
As for the rest, you are currently alone here. There are a lot of existing
modules, use a simple module as a starting point and add your own code.
CREATING THE SELF-CONTAINED EXTENSION
Put config.m4 and the source files into one directory. Afterwards,
run phpize (this is installed during make install by PHP 4.0).
For example, if you configured PHP with --prefix=/php, you would run
$ /php/bin/phpize
This will automatically copy the necessary build files and create
configure from your config.m4.
And that's it. You now have a self-contained extension.
INSTALLING A SELF-CONTAINED EXTENSION
An extension can be installed by running:
$ ./configure \
[--with-php-config=/path/to/php-config]
$ make install
ADDING SHARED MODULE SUPPORT TO A MODULE
In order to be useful, a self-contained extension must be loadable
as a shared module. I will explain now how you can add shared module
support to an existing module called foo.
1. In config.m4, use PHP_ARG_WITH/PHP_ARG_ENABLE. Then you will
automatically be able to use --with-foo=shared[,..] or
--enable-foo=shared[,..].
2. In config.m4, use PHP_NEW_EXTENSION(foo,.., $ext_shared) to enable
building the extension.
3. Add the following lines to your C source file:
#ifdef COMPILE_DL_FOO
ZEND_GET_MODULE(foo)
#endif

An Overview of the PHP Streams abstraction
==========================================
$Id$
Please send comments to: Wez Furlong <wez@thebrainroom.com>
Why Streams?
============
You may have noticed a shed-load of issock parameters flying around the PHP
code; we don't want them - they are ugly and cumbersome and force you to
special case sockets and files everytime you need to work with a "user-level"
PHP file pointer.
Streams take care of that and present the PHP extension coder with an ANSI
stdio-alike API that looks much nicer and can be extended to support non file
based data sources.
Using Streams
=============
Streams use a php_stream* parameter just as ANSI stdio (fread etc.) use a
FILE* parameter.
The main functions are:
PHPAPI size_t php_stream_read(php_stream * stream, char * buf, size_t count);
PHPAPI size_t php_stream_write(php_stream * stream, const char * buf, size_t
count);
PHPAPI int php_stream_eof(php_stream * stream);
PHPAPI int php_stream_getc(php_stream * stream);
PHPAPI char *php_stream_gets(php_stream * stream, char *buf, size_t maxlen);
PHPAPI int php_stream_close(php_stream * stream);
PHPAPI int php_stream_flush(php_stream * stream);
PHPAPI int php_stream_seek(php_stream * stream, off_t offset, int whence);
PHPAPI off_t php_stream_tell(php_stream * stream);
These (should) behave in the same way as the ANSI stdio functions with similar
names: fread, fwrite, feof, fgetc, fgets, fclose, fflush, fseek, ftell.
Opening Streams
===============
In most cases, you should use this API:
PHPAPI php_stream *php_stream_open_wrapper(char *path, char *mode,
int options, char **opened_path TSRMLS_DC);
Where:
path is the file or resource to open.
mode is the stdio compatible mode eg: "wb", "rb" etc.
options is a combination of the following values:
IGNORE_PATH (default) - don't use include path to search for the file
USE_PATH - use include path to search for the file
IGNORE_URL - do not use plugin wrappers
REPORT_ERRORS - show errors in a standard format if something
goes wrong.
STREAM_MUST_SEEK - If you really need to be able to seek the stream
and don't need to be able to write to the original
file/URL, use this option to arrange for the stream
to be copied (if needed) into a stream that can
be seek()ed.
opened_path is used to return the path of the actual file opened,
but if you used STREAM_MUST_SEEK, may not be valid. You are
responsible for efree()ing opened_path. opened_path may be (and usually
is) NULL.
If you need to open a specific stream, or convert standard resources into
streams there are a range of functions to do this defined in php_streams.h.
A brief list of the most commonly used functions:
PHPAPI php_stream *php_stream_fopen_from_file(FILE *file, const char *mode);
Convert a FILE * into a stream.
PHPAPI php_stream *php_stream_fopen_tmpfile(void);
Open a FILE * with tmpfile() and convert into a stream.
PHPAPI php_stream *php_stream_fopen_temporary_file(const char *dir,
const char *pfx, char **opened_path TSRMLS_DC);
Generate a temporary file name and open it.
There are some network enabled relatives in php_network.h:
PHPAPI php_stream *php_stream_sock_open_from_socket(int socket, int persistent);
Convert a socket into a stream.
PHPAPI php_stream *php_stream_sock_open_host(const char *host, unsigned short port,
int socktype, int timeout, int persistent);
Open a connection to a host and return a stream.
PHPAPI php_stream *php_stream_sock_open_unix(const char *path, int persistent,
struct timeval *timeout);
Open a UNIX domain socket.
Stream Utilities
================
If you need to copy some data from one stream to another, you will be please
to know that the streams API provides a standard way to do this:
PHPAPI size_t php_stream_copy_to_stream(php_stream *src,
php_stream *dest, size_t maxlen);
If you want to copy all remaining data from the src stream, pass
PHP_STREAM_COPY_ALL as the maxlen parameter, otherwise maxlen indicates the
number of bytes to copy.
This function will try to use mmap where available to make the copying more
efficient.
If you want to read the contents of a stream into an allocated memory buffer,
you should use:
PHPAPI size_t php_stream_copy_to_mem(php_stream *src, char **buf,
size_t maxlen, int persistent);
This function will set buf to the address of the buffer that it allocated,
which will be maxlen bytes in length, or will be the entire length of the
data remaining on the stream if you set maxlen to PHP_STREAM_COPY_ALL.
The buffer is allocated using pemalloc(); you need to call pefree() to
release the memory when you are done.
As with copy_to_stream, this function will try use mmap where it can.
If you have an existing stream and need to be able to seek() it, you
can use this function to copy the contents into a new stream that can
be seek()ed:
PHPAPI int php_stream_make_seekable(php_stream *origstream, php_stream **newstream);
It returns one of the following values:
#define PHP_STREAM_UNCHANGED 0 /* orig stream was seekable anyway */
#define PHP_STREAM_RELEASED 1 /* newstream should be used; origstream is no longer valid */
#define PHP_STREAM_FAILED 2 /* an error occurred while attempting conversion */
#define PHP_STREAM_CRITICAL 3 /* an error occurred; origstream is in an unknown state; you should close origstream */
make_seekable will always set newstream to be the stream that is valid
if the function succeeds.
When you have finished, remember to close the stream.
NOTE: If you only need to seek forwards, there is no need to call this
function, as the php_stream_seek can emulate forward seeking when the
whence parameter is SEEK_CUR.
NOTE: Writing to the stream may not affect the original source, so it
only makes sense to use this for read-only use.
NOTE: If the origstream is network based, this function will block
until the whole contents have been downloaded.
NOTE: Never call this function with an origstream that is referenced
as a resource! It will close the origstream on success, and this
can lead to a crash when the resource is later used/released.
NOTE: If you are opening a stream and need it to be seekable, use the
STREAM_MUST_SEEK option to php_stream_open_wrapper();
Casting Streams
===============
What if your extension needs to access the FILE* of a user level file pointer?
You need to "cast" the stream into a FILE*, and this is how you do it:
FILE * fp;
php_stream * stream; /* already opened */
if (php_stream_cast(stream, PHP_STREAM_AS_STDIO, (void*)&fp, REPORT_ERRORS) == FAILURE) {
RETURN_FALSE;
}
The prototype is:
PHPAPI int php_stream_cast(php_stream * stream, int castas, void ** ret, int
show_err);
The show_err parameter, if non-zero, will cause the function to display an
appropriate error message of type E_WARNING if the cast fails.
castas can be one of the following values:
PHP_STREAM_AS_STDIO - a stdio FILE*
PHP_STREAM_AS_FD - a generic file descriptor
PHP_STREAM_AS_SOCKETD - a socket descriptor
If you ask a socket stream for a FILE*, the abstraction will use fdopen to
create it for you. Be warned that doing so may cause buffered data to be lost
if you mix ANSI stdio calls on the FILE* with php stream calls on the stream.
If your system has the fopencookie function, php streams can synthesize a
FILE* on top of any stream, which is useful for SSL sockets, memory based
streams, data base streams etc. etc.
In situations where this is not desireable, you should query the stream
to see if it naturally supports FILE *. You can use this code snippet
for this purpose:
if (php_stream_is(stream, PHP_STREAM_IS_STDIO)) {
/* can safely cast to FILE* with no adverse side effects */
}
You can use:
PHPAPI int php_stream_can_cast(php_stream * stream, int castas)
to find out if a stream can be cast, without actually performing the cast, so
to check if a stream is a socket you might use:
if (php_stream_can_cast(stream, PHP_STREAM_AS_SOCKETD) == SUCCESS) {
/* it can be a socket */
}
Please note the difference between php_stream_is and php_stream_can_cast;
stream_is tells you if the stream is a particular type of stream, whereas
can_cast tells you if the stream can be forced into the form you request.
The former doesn't change anything, while the later *might* change some
state in the stream.
Stream Internals
================
There are two main structures associated with a stream - the php_stream
itself, which holds some state information (and possibly a buffer) and a
php_stream_ops structure, which holds the "virtual method table" for the
underlying implementation.
The php_streams ops struct consists of pointers to methods that implement
read, write, close, flush, seek, gets and cast operations. Of these, an
implementation need only implement write, read, close and flush. The gets
method is intended to be used for streams if there is an underlying method
that can efficiently behave as fgets. The ops struct also contains a label
for the implementation that will be used when printing error messages - the
stdio implementation has a label of "STDIO" for example.
The idea is that a stream implementation defines a php_stream_ops struct, and
associates it with a php_stream using php_stream_alloc.
As an example, the php_stream_fopen() function looks like this:
PHPAPI php_stream * php_stream_fopen(const char * filename, const char * mode)
{
FILE * fp = fopen(filename, mode);
php_stream * ret;
if (fp) {
ret = php_stream_alloc(&php_stream_stdio_ops, fp, 0, 0, mode);
if (ret)
return ret;
fclose(fp);
}
return NULL;
}
php_stream_stdio_ops is a php_stream_ops structure that can be used to handle
FILE* based streams.
A socket based stream would use code similar to that above to create a stream
to be passed back to fopen_wrapper (or it's yet to be implemented successor).
The prototype for php_stream_alloc is this:
PHPAPI php_stream * php_stream_alloc(php_stream_ops * ops, void * abstract,
size_t bufsize, int persistent, const char * mode)
ops is a pointer to the implementation,
abstract holds implementation specific data that is relevant to this instance
of the stream,
bufsize is the size of the buffer to use - if 0, then buffering at the stream
level will be disabled (recommended for underlying sources that implement
their own buffering - such a FILE*),
persistent controls how the memory is to be allocated - persistently so that
it lasts across requests, or non-persistently so that it is freed at the end
of a request (it uses pemalloc),
mode is the stdio-like mode of operation - php streams places no real meaning
in the mode parameter, except that it checks for a 'w' in the string when
attempting to write (this may change).
The mode parameter is passed on to fdopen/fopencookie when the stream is cast
into a FILE*, so it should be compatible with the mode parameter of fopen().
Writing your own stream implementation
======================================
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
RULE #1: when writing your own streams: make sure you have configured PHP with
--enable-debug.
I've taken some great pains to hook into the zend memory manager to help track
down allocation problems. It will also help you spot incorrect use of the
STREAMS_DC, STREAMS_CC and the semi-private STREAMS_REL_CC macros for function
definitions.
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
RULE #2: Please use the stdio stream as a reference; it will help you
understand the semantics of the stream operations, and it will always
be more up to date than these docs :-)
First, you need to figure out what data you need to associate with the
php_stream. For example, you might need a pointer to some memory for memory
based streams, or if you were making a stream to read data from an RDBMS like
mysql, you might want to store the connection and rowset handles.
The stream has a field called abstract that you can use to hold this data.
If you need to store more than a single field of data, define a structure to
hold it, allocate it (use pemalloc with the persistent flag set
appropriately), and use the abstract pointer to refer to it.
For structured state you might have this:
struct my_state {
MYSQL conn;
MYSQL_RES * result;
};
struct my_state * state = pemalloc(sizeof(struct my_state), persistent);
/* initialize the connection, and run a query, using the fields in state to
* hold the results */
state->result = mysql_use_result(&state->conn);
/* now allocate the stream itself */
stream = php_stream_alloc(&my_ops, state, 0, persistent, "r");
/* now stream->abstract == state */
Once you have that part figured out, you can write your implementation and
define the your own php_stream_ops struct (we called it my_ops in the above
example).
For example, for reading from this wierd mysql stream:
static size_t php_mysqlop_read(php_stream * stream, char * buf, size_t count)
{
struct my_state * state = (struct my_state*)stream->abstract;
if (buf == NULL && count == 0) {
/* in this special case, php_streams is asking if we have reached the
* end of file */
if (... at end of file ...)
return EOF;
else
return 0;
}
/* pull out some data from the stream and put it in buf */
... mysql_fetch_row(state->result) ...
/* we could do something strange, like format the data as XML here,
and place that in the buf, but that brings in some complexities,
such as coping with a buffer size too small to hold the data,
so I won't even go in to how to do that here */
}
Implement the other operations - remember that write, read, close and flush
are all mandatory. The rest are optional. Declare your stream ops struct:
php_stream_ops my_ops = {
php_mysqlop_write, php_mysqlop_read, php_mysqlop_close,
php_mysqlop_flush, NULL, NULL, NULL,
"Strange mySQL example"
}
Thats it!
Take a look at the STDIO implementation in streams.c for more information
about how these operations work.
The main thing to remember is that in your close operation you need to release
and free the resources you allocated for the abstract field. In the case of
the example above, you need to use mysql_free_result on the rowset, close the
connection and then use pefree to dispose of the struct you allocated.
You may read the stream->persistent field to determine if your struct was
allocated in persistent mode or not.

Submitting Patch for PHP
========================
This document describes how to submit a patch for PHP. Since you are
reading this document, you are willing to submit a patch for PHP.
Please keep reading! Submitting a patch for PHP is easy. The hard
part is making it acceptable for inclusion into our repository. :-)
How to create patch?
--------------------
We are working with CVS. You need to get CVS source to create a patch
that we accept. Visit http://www.php.net/anoncvs.php to get CVS
source. You can check out older versions, but make sure you get
the default branch (i.e. Do not use -r option when you check out the
CVS source)
Read CODING_STANDARDS file before you start working.
Now you are ready to create a patch. Modify source to fix a bug in PHP or
add a new feature to PHP. After you finished editing, please test your
patch. Read README.TESTING for testing.
After you finish testing your patch, take diff file using
"cvs diff > your.patch" command.
Read README.TESTING for submitting a test script for your patch. This is
not strictly required, but it is preferred to submit a test script along
with your patch. Making new test script is very easy. It also helps us
to understand what you have been fixed or added to PHP.
Tips for creating patch
-----------------------
If you would like to fix multiple bugs. It is easier for us if you
could create 1 patch for 1 bug, but this is not strictly required.
Note though that you might get little response, if your patch is
too hard to review.
If you would like change/add many lines, it is better to ask module
maintainer and/or php-dev@lists.php.net, or pear-dev@lists.php.net if
you are patching PEAR. Official module maintainers can be found in
EXTENSIONS file in PHP source.
If you are new to CVS (Concurrent Versions System), visit
http://cvshome.org/ for details.
Recommended CVS client settings for creating patch file
------------------------------------------------------
Recommended ~/.cvsrc file setting is:
------
cvs -z3
update -d -P
checkout -P
diff -u
------
diff -u means:
-u Use the unified output format.
With this CVS setting, you don't have to worry about adding/deleting
newlines and spaces.
Check list for submitting patch
-------------------------------
- Did you run "make test" to check if your patch didn't break
other features?
- Did you compile PHP with --enable-debug and check php/webserver
error logs when you test your patch?
- Did you build PHP for multi-threaded web servers. (Optional)
- Did you create test script for "make test"? (Recommended)
- Did you check your patch is unified format and it does not
contain white space changes? (If you are not using recommended
cvs setting)
- Did you update CVS source before you take final patch?
- Did you read the patch again?
Where to send your patch?
-------------------------
If you are patching C source, send the patch to php-dev@lists.php.net.
If you are patching a module, you should also send the patch to the
maintainer. Official module maintainers are listed in EXTENSION file
in source.
If you are patching PEAR, send the patch to pear-dev@lists.php.net.
Please add the prefix "[PATCH]" to your email subject and make sure
to include the patch as a MIME attachment even if it is short.
Test scripts should be included in the same email.
Explain what has been fixed/added/changed by your patch.
Finally, add the bug Id(s) which can be closed by your patch, if any.
What happens after you submit your patch
--------------------------------------
If your patch is easy to review and has obviously no side-effects,
it might take up to a few hours until someone commits it.
Because this is a volunteer-driven effort, more complex patches will
require more patience on your side.
If you did not receive any feedback in a few days, please consider
resubmitting the description of your patch, along-side with
these questions:
- Is my patch too hard to review? Because of which factors?
- Should I split it up in multiple parts?
- Are there any unwanted whitespace changes?
What happens when your patch is applied?
----------------------------------------
Your name will be included together with your email address in the CVS
commit log. If your patch affects end-users, a brief description
and your name might be added to the NEWS file.
Thank you for submitting patch for PHP!

[IMPORTANT NOTICE]
------------------
Do _not_ ask to developers why some or all tests are failed under
your environment! Let us know if you find why it fails. Thank you.
[Testing Basics]
----------------
To execute test scripts, you must build PHP with some SAPI, then you
type "make test" to execute all or some test scripts saved under
"tests" directory under source root directory.
Usage:
make test
"make test" basically executes "run-tests.php" script
under source root. Therefore you can execute the script
as follows
./sapi/cli/php -c /path/to/php.ini/ run-tests.php [ext/some_extension_name]
[Which "php" executable "make test" look for]
---------------------------------------------
"make test" executes "run-tests.php" script with "php" binary. Some
test scripts such as session must be executed by CGI SAPI. Therefore,
you must build PHP with CGI SAPI to perform all tests.
If PHP is not build with CGI SAPI, "run-tests.php" script uses CLI
SAPI. Tests that may not executed by CLI SAPI will be skipped.
NOTE: PHP binary executing "run-tests.php" and php binary used for
executing test scripts may differ. If you use different PHP binary for
executing "run-tests.php" script, you may get errors.
[Which php.ini is used]
-----------------------
"make test" force to use php.ini-dist as default config file. If
you would like to test with other configuration file, user
"run-tests.php" script.
Example:
./sapi/cli/php -c /path/to/php.ini/ ext/standard
If you use php.ini other than php.ini-dist, you may see more failed
tests.
[Which test scripts are executed]
---------------------------------
"run-tests.php" ("make test") executes all test scripts by default
by looking all directory named "tests". If there are files have "phpt"
extension, "run-tests.php" takes test php code from the file and
executes it.
Tester can easily executes tests selectively with as follows.
Example:
./sapi/cli/php -c /path/to/php.ini/ run-tests.php ext/mbstring
[Test results]
--------------
Test results are printed to standard output. If there is a failed test,
"run-tests.php" script saves the result, expected result and code
executed to the test script directory. For example, if
ext/myext/tests/myext.phpt is failed to pass, following files are
created:
ext/myext/tests/myext.out - output from test script
ext/myext/tests/myext.exp - expected output
ext/myext/tests/myext.php - test script executed
Tester can verify these files, if failed test is actually a bug
or not.
[Creating new test files]
-------------------------
Writing test file is very easy if you are used to PHP. Test file
has following format. Here is a actual test file from iconv module.
===== ext/iconv/002.phpt =======
--TEST--
UCS4BE to ASCII
--SKIPIF--
<?php include('skipif.inc'); ?>
--POST--
--GET--
--FILE--
<?php include('002.inc'); ?>
--EXPECT--
&#97;&#98;&#99;&#100;
abcd
===== end of ext/iconv/002.phpt =======
"--TEST--" is title of the test.
"--SKIPIF--" is condition when to skip this test.
"--POST--" is POST variable passed to test script.
"--GET--" is GET variable passed to test script.
"--FILE--" is the test script.
"--EXPECT--" is the expected output from the test script.
ext/iconv/002.phpt uses 2 files. "skipif.inc" is used to skip
test when test cannot be performed such as iconv module is not
compiled or loaded.
==== ext/iconv/skipif.inc ====
<?php
// This script prints "skip" if condition does not meet.
if (!extension_loaded("iconv") && ini_get("enable_dl")) {
$dlext = (substr(PHP_OS, 0, 3) == "WIN") ? ".dll" : ".so";
@dl("iconv$dlext");
}
if (!extension_loaded("iconv")) {
die("skip\n");
}
?>
==== end of ext/iconv/skipif.inc ====
ext/inconv/002.inc is the test script. "run-tests.php" script
executes test script with CGI executable.
==== ext/iconv/002.inc ===
<?php
/*
Expected output:
&#97;&#98;&#99;&#100;
abcd
*/
$s = unpack("V*", iconv("ascii","UCS-4LE", "abcd"));
foreach($s as $c) { print "&#$c;"; } print "\n";
$s = pack("NNNN", 97, 98, 99, 100);
$q = iconv("UCS-4BE", "ascii", $s);
print $q; print "\n";
?>
=== end of ext/iconv/002.inc ===
Test script and skipif code may be directly write into *.phpt.
However, it is recommended to use other files for ease of writing
test script. For instance, you can execute test script under
ext/iconv as follows:
./sapi/cli/php -c /path/to/php.ini/ ext/iconv
[How to help us]
----------------
If you find bug in PHP, you can submit bug report AND test script
for us. You don't have to write complete script, just give us test
script with following format. Please test the script and make sure
you write the correct ACTUAL OUTPUT and EXPECTED OUTPUT before you
submit.
<?php
/*
Bug #12345
substr() bug. Do not return expected string.
ACTUAL OUTPUT
XYXA
EXPECTED OUTPUT
ABCD
*/
$str = "XYZABCD";
echo substr($str,3,7);
?>

PHP Build System V5 Overview
- supports Makefile.ins during transition phase
- not-really-portable Makefile includes have been eliminated
- supports seperate build directories without VPATH by using
explicit rules only
- does not waste disk-space/CPU-time for building temporary libraries
=> especially noticeable on slower systems
- slow recursive make replaced with one global Makefile
- eases integration of proper dependencies
- adds PHP_DEFINE(what[, value]) which creates a single include-file
per what. This will allow more fine-grained dependencies.
- abandoning the "one library per directory" concept
- improved integration of the CLI
- several new targets
build-modules: builds and copies dynamic modules into modules/
install-cli: installs the CLI only, so that the install-sapi
target does only what its name says
- finally abandoned automake (still requires aclocal at this time)
- changed some configure-time constructs to run at buildconf-time
- upgraded shtool to 1.5.4
- removed $(moduledir) (use EXTENSION_DIR)
The Reason For a New System
It became more and more apparent that there is a severe need
for addressing the portability concerns and improving the chance
that your build is correct (how often have you been told to
"make clean"? When this is done, you won't need to anymore).
If You Build PHP on a Unix System
You, as a user of PHP, will notice no changes. Of course, the build
system will be faster, look better and work smarter.
If You Are Developing PHP
Extension developers:
Makefile.ins are abandoned. The files which are to be compiled
are specified in the config.m4 now using the following macro:
PHP_NEW_EXTENSION(foo, foo.c bar.c baz.cpp, $ext_shared)
E.g. this enables the extension foo which consists of three source-code
modules, two in C and one in C++. And dependending on the user's
wishes, the extension will even be built as a dynamic module.
The full syntax:
PHP_NEW_EXTENSION(extname, sources [, shared [,sapi_class[, extra-cflags]]])
Please have a look at acinclude.m4 for the gory details and meanings
of the other parameters.
And that's basically it for the extension side.
If you previously built sub-libraries for this module, add
the source-code files here as well. If you need to specify
separate include directories, do it this way:
PHP_NEW_EXTENSION(foo, foo.c mylib/bar.c mylib/gregor.c,,,-I@ext_srcdir@/lib)
E.g. this builds the three files which are located relative to the
extension source directory and compiles all three files with the
special include directive (@ext_srcdir@ is automatically replaced).
Now, you need to tell the build system that you want to build files
in a directory called $ext_builddir/lib:
PHP_ADD_BUILD_DIR($ext_builddir/lib)
Make sure to call this after PHP_NEW_EXTENSION, because $ext_builddir
is only set by the latter.
If you have a complex extension, you might to need add special
Make rules. You can do this by calling PHP_ADD_MAKEFILE_FRAGMENT
in your config.m4 after PHP_NEW_EXTENSION.
This will read a file in the source-dir of your extension called
Makefile.frag. In this file, $(builddir) and $(srcdir) will be
replaced by the values which are correct for your extension
and which are again determined by the PHP_NEW_EXTENSION macro.
Make sure to prefix *all* relative paths correctly with either
$(builddir) or $(srcdir). Because the build system does not
change the working directory anymore, we must use either
absolute paths or relative ones to the top build-directory.
Correct prefixing ensures that.
SAPI developers:
Instead of using PHP_SAPI=foo/PHP_BUILD_XYZ, you will need to type
PHP_SELECT_SAPI(name, type, sources.c)
I.e. specify the source-code files as above and also pass the
information regarding how PHP is supposed to be built (shared
module, program, etc).
For example for APXS:
PHP_SELECT_SAPI(apache, shared, sapi_apache.c mod_php4.c php_apache.c)
General info
The foundation for the new system is the flexible handling of
sources and their contexts. With the help of macros you
can define special flags for each source-file, where it is
located, in which target context it can work, etc.
Have a look at the well documented macros
PHP_ADD_SOURCES(_X) in acinclude.m4.

Using PHP4 with the Zeus Web Server
-----------------------------------
Zeus fully supports running PHP in combination with our
webserver. There are three different interfaces that can be used to
enable PHP:
* CGI
* ISAPI
* FastCGI
Of the three, we recommend using FastCGI, which has been tested and
benchmarked as providing the best performance and reliability.
Full details of how to install PHP are available from our
website, at:
http://support.zeus.com/products/php.html
If you have any problems, please check the support site for more
up-to-date information and advice.
Quick guide to installing FastCGI with Zeus
-------------------------------------------
Step 1 - obtain and install FastCGI development kit.
Grab the package from:
http://www.fastcgi.com/dist/devkit_2.2.0.tar.gz
Extract the package and follow the instructions:
./configure
make
make export
(run the last as root)
This will install to /usr/local/lib/libfcgi.a
and /usr/local/include/*fcgi*
Step 2 - Compile PHP as FastCGI.
Compile as follows:
./configure --with-fastcgi
make
Note that PHP has many options to the configure script -
e.g. --with-mysql. You will probably want to select your usual options
before compiling; the above is just a bare minimum, for illustration.
After compilation finishes, you will be left with an executable
program called 'php'. Copy this into your document root, under a
dedicated FastCGI directory (e.g. $DOCROOT/fcgi-bin/php)
Step 3 - configure Zeus
Four stages:
- enable FastCGI
- configure FastCGI
- setup alias for FastCGI
- setup alias for PHP
1) Using the admin server, go to the 'module configuration' page for
your virtual server, and ensure that 'fastcgi' is enabled (select the
tickbox to the left).
2) While we can run FastCGI's locally, there are known problems with
some OS's (specifically, the communication between web server and
FastCGI happens over a unix domain socket, and some OS's have trouble
sustaining high connection rates over these sockets). So instead, we
are going to set up the PHP FastCGI to run 'remotely' over localhost
(this uses TCP sockets, which do not suffer this problem). Go to the
'fastcgi configuration' page, and under 'add remote fastcgi':
Add Remote FastCGI
Docroot path /fcgi-bin/php
Remote machine localhost:8002
The first entry is where you saved PHP, above.
The second entry is localhost:<any unused port>
We will start the FastCGI listening on this port shortly.
Click 'update' to commit these changes.
3) Go to the path mapping module and add an alias for FastCGI:
Add Alias
Docroot path /fcgi-bin
Filesystem directory /path/to/docroot/fcgi-bin
Alias type fastcgi
Click 'update' to commit these changes
4) Also on the path mapping module, add a handler for PHP:
Add handler
File extension php
Handler /fcgi-bin/php
Click 'update' to commit these changes
Finally restart your virtual server for these changes to take effect.
Step 4 - start PHP as a FastCGI runner
When you start PHP, it will pre-fork a given number of child processes
to handle incoming PHP requests. Each process will handle a given
number of requests before exiting (and being replaced by a newly
forked process). You can control these two parameters by setting the
following environment variables BEFORE starting the FastCGI runner:
PHP_FCGI_CHILDREN - the number of child processes to pre-fork. If not
set, defaults to 8.
PHP_FCGI_MAX_REQUESTS - the number of requests each PHP child process
handles before exiting. If not set, defaults to 500.
To start the FastCGI runner, execute '$ZEUSHOME/web/bin/fcgirunner
8002 $DOCROOT/fcgi-bin/php'. Substitute the appropriate values for
$ZEUSHOME and $DOCROOT; also substitute for 8002 the port you chose,
above.
To stop the runner (e.g. to experiment with the above environment
variables) you will need to manually stop and running PHP
processes. (Use 'ps' and 'kill'). As it is PHP which is forking lots
of children and not the runner, Zeus unfortunately cannot keep track
of what processes are running, sorry. A typical command line may look
like 'ps -efl | grep $DOCROOT/fcgi-bin/php | grep -v grep | awk
'{print $4}' | xargs kill'

Things to do or at least think about doing in the future. Name in
parenthesis means that person has taken on this project.
Zend
----
For PHP 4.3.0:
* Allow foreach ($array as $k => &$val) syntax. right now we cannot
traverse an array without copying each element.
* Allow foreach ($array as $k => list($a, $b)) syntax for multi
dimensional arrays.
* Look at replacing c-lib call tolower().
* Make hash API functions work with HASH_OF() to save time.
* Allow to set a default value for call-by-reference-parameters.
eg: function hello (&$pallo = NULL) {}
* Disallow function(method) redefinition in class.
* Add configure test to determine if dlsym() requires underscore and set
DLSYM_NEEDS_UNDERSCORE accordingly. Perl and zsh have it in configure,
for example. (DONE?)
For PHP 5.0.0:
* Native large number support (probably with GNU GMP)
* Const'ify APIs. Right now, many functions leave parameters untouched,
but don't declare those as const. This makes interaction with other
interfaces difficult which pass const parameters to us.
global
------
For PHP 4.3.0:
* Add aliases to functions to conform to new naming conventions, e.g.
str_to_upper().
* Make all extensions thread-safe.
* Make everything on the language-level independent of your locale
settings.
* Change PHP error messages, so that they point to pages or sections
in the PHP Manual.
* Make sure that all ZTS globals get destructed. Most ts_allocate_id()
calls should have a dtor entry.
* Activate all extensions by default that don't rely on external
dependencies. (eg ftp) (DONE?)
* on some platforms unimplemented function will just do nothing
(e.g. symlink) they should print a warning or not even be defined!
(DONE ?)
* Use arg_separator.input to implode args in the CGI sapi extension
and arg_separator.input to explode in php_build_argv(). (DONE?)
* Change the odbc_fetch_into() function to require ALWAYS the first two
parameters ($conn_id and $array), and make the third (row) be optional.
* Remove --with-openlink configure option (--with-iodbc replaces it).
* Implement flush feature suitable for nested output buffers.
For PHP 5.0.0
* bundle and use curl lib for fopen wrapper.
* --enable-all in configure. (--enable-shared=max ...)
* make configure print out a summary when it's done (like XEmacs)
* replace standard functions which work on static data with
reentrancy-safe functions (DONE?).
* make SAPI conform to CGI/1.1. Currently, all SAPI modules
define REMOTE_ADDR etc. themselves and reach only various level
of compliance.
* see what functions might need to be changed to use HashPosition, so
that the internal array pointer is not affected.
* Move most extensions and PEAR packages out of the PHP CVS tree,
include them again during release packaging.
Other
* use thread-safe resolver functions (either require BIND 8 or adns).
* implement javadoc based function docs template system.
* provide optional IPv6 support.
* find a better way to implement script timeouts. SIGVTALRM is used
by some POSIX threads implementations (i.e. OpenBSD) and is not
available in ZTS mode.
documentation
-------------
* Add remarks in the documentation which functions are not implemented
on win32.
* Add remarks in the documentation which functions are not binary-safe.
* Update curl documentation (DONE?)
* Add developer documentation.
* Add detailed documentation for Java extension.
ext/bz2
-------
* Add ini setting for decompression buffer size. The default 4k is to small
for big files and takes ages to decompress. However, 40k which perform
quite good with big files may be to much under certain environments as
default setting. There should be consideren different default sizes for
different SAPIS (e.g. apache and cli).
ext/curl
--------
* Have a warning scheme for when people use unsupported features.
ext/oci8
--------
* All OCIFetch*() functions should return 0 for no more data and false on
error.
* Have a flag that trims trailing spaces from CHAR fields on retrieval.
* Make allow_call_time_pass_reference=Off working.
* For additional todo information, see oci8.c, in ext/oci8
ext/pcre
--------
* Allow user to set PCRE_NOTEMPTY, PCRE_ANCHORED at execution time, maybe
ext/pcntl
---------
* Change internal callback handler to use TICKS
* Remove all zend_extension code
* Add object callback support to pcntl_signal()
ext/pgsql
---------
For PHP 4.3.0:
* Add pg_metadata() with metadata cache feature.
* Add pg_convert() to check and convert array value for query.
* Add pg_insert/pg_update/pg_delete/pg_select for simple query.
ext/session
-----------
For PHP 4.3.0:
* session_abort() to abort session. ie: Do not save session data.
* Allow unset($_SESSION) or unset($HTTP_SESSION_VARS) to unset
session vars regardless of register_globals setting.
Other:
* Maybe implement finer-grained session variables that could be
locked individually.
* Write a network-transparent storage back-end with fallover
facilities
* Provide a callback facility which is executed upon encountering
an unknown class name during deserialization
ext/sockets
-----------
* Implement IPv6
* Review/Fix vectors
ext/standard
------------
* Add a version number to data serialized via serialize().
* Possibly modify parsing of GPC data to automatically create arrays if
variable name is seen more than once.
* Implement regex-cache for url-functions.
* stri_replace(). (Andrei)
* Move socket related functions to fsock.c.
* NOT binary safe:
strtok()
basename()
dirname()
strrpos()
strrchr()
strip_tags()
ext/wddx
--------
* See if we can support the remaining data types:
dateTime
binary
http://www.wddx.org/WDDX_SDK_10a/7__References/WDDX_DTD.htm
(Andrei)
* implement wddx_packet_as_javascript(). (Andrei)
other cool stuff

Following is a merge of two letters I sent to php4beta@lists.php.net,
describing the changes in API between PHP 3.0 and PHP 4.0 (Zend).
This file is by no means thorough documentation of the PHP API,
and is intended for developers who are familiar with the PHP 3.0 API,
and want to port their code to PHP 4.0, or take advantage of its new
features. For highlights about the PHP 3.0 API, consult apidoc.txt.
Zeev
--------------------------------------------------------------------------
I'm going to try to list the important changes in API and programming
techniques that are involved in developing modules for PHP4/Zend, as
opposed to PHP3. Listing the whole PHP4 API is way beyond my scope here,
it's mostly a 'diff' from the apidoc.txt, which you're all pretty familiar
with.
An important note that I neglected to mention yesterday - the php4 tree is
based on the php 3.0.5 tree, plus all 3.0.6 patches hand-patched into it.
Notably, it does NOT include any 3.0.7 patches. All of those have to be
reapplied, with extreme care - modules should be safe to patch (mostly),
but anything that touches the core or main.c will almost definitely require
changes in order to work properly.
[1] Symbol Tables
One of the major changes in Zend involves changing the way symbols tables
work. Zend enforces reference counting on all values and resources. This
required changes in the semantics of the hash tables that implement symbol
tables. Instead of storing pval in the hashes, we now store pval *. All
of the API functions in Zend were changed in a way that this change is
completely transparent. However, if you've used 'low level' hash functions
to access or update elements in symbol tables, your code will require
changes. Following are two simple examples, one demonstrates the
difference between PHP3 and Zend when reading a symbol's value, and the
other demonstrates the difference when writing a value.
php3_read()
{
pval *foo;
_php3_hash_find(ht, "foo", sizeof("foo"), &foo);
/* foo->type is the type and foo->value is the value */
}
php4_read()
{
pval **foo;
_php3_hash_find(ht, "foo", sizeof("foo"), &foo);
/* (*foo)->type is the type and (*foo)->value is the value */
}
---
php3_write()
{
pval newval;
newval.type = ...;
newval.value = ...;
_php3_hash_update(ht, "bar", sizeof("bar"), &newval, sizeof(pval), NULL);
}
php4_write()
{
pval *newval = ALLOC_ZVAL();
newval->refcount=1;
newval->is_ref=0;
newval->type = ...;
newval->value = ...;
_php3_hash_update(ht, "bar", sizeof("bar"), &newval, sizeof(pval *), NULL);
}
[2] Resources
One of the 'cute' things about the reference counting support is that it
completely eliminates the problem of resource leaking. A simple loop that
included '$result = mysql_query(...)' in PHP leaked unless the user
remembered to run mysql_free($result) at the end of the loop body, and
nobody really did. In order to take advantage of the automatic resource
deallocation upon destruction, there's virtually one small change you need
to conduct. Change the result type of a resource that you want to destroy
itself as soon as its no longer referenced (just about any resource I can
think of) as IS_RESOURCE, instead of as IS_LONG. The rest is magic.
A special treatment is required for SQL modules that follow MySQL's
approach for having the link handle as an optional argument. Modules that
follow the MySQL module model, store the last opened link in a global
variable, that they use in case the user neglects to explicitly specify a
link handle. Due to the way referenec counting works, this global
reference is just like any other reference, and must increase that SQL link
resource's reference count (otherwise, it will be closed prematurely).
Simply, when you set the default link to a certain link, increase that
link's reference count by calling zend_list_addref().
As always, the MySQL module is the one used to demonstrate 'new
technology'. You can look around it and look for IS_RESOURCE, as well as
zend_list_addref(), to see a clear example of how the new API should be used.
[3] Thread safety issues
I'm not going to say that Zend was designed with thread safety in mind, but
from some point, we've decided upon several guidelines that would make the
move to thread safety much, much easier. Generally, we've followed the PHP
3.1 approach of moving global variables to a structure, and encapsulating
all global variable references within macros. There are three main
differences:
1. We grouped related globals in a single structure, instead of grouping
all globals in one structure.
2. We've used much, much shorter macro names to increase the readability
of the source code.
3. Regardless of whether we're compiling in thread safe mode or not, all
global variables are *always* stored in a structure. For example, you
would never have a global variable 'foo', instead, it'll be a property of a
global structure, for example, compiler_globals.foo. That makes
development much, much easier, since your code will simply not compile
unless you remember to put the necessary macro around foo.
To write code that'll be thread safe in the future (when we release our
thread safe memory manager and work on integrating it), you can take a look
at zend_globals.h. Essentially, two sets of macros are defined, one for
thread safe mode, and one for thread unsafe mode. All global references
are encapsulated within ???G(varname), where ??? is the appropriate prefix
for your structure (for example, so far we have CG(), EG() and AG(), which
stand for the compiler, executor and memory allocator, respectively).
When compiling with thread safety enabled, each function that makes use of
a ???G() macro, must obtain the pointer to its copy of the structure. It
can do so in one of two forms:
1. It can receive it as an argument.
2. It can fetch it.
Obviously, the first method is preferable since it's much quicker.
However, it's not always possible to send the structure all the way to a
particular function, or it may simply bloat the code too much in some
cases. Functions that receive the globals as an argument, should look like
this:
rettype functioname(???LS_D) <-- a function with no arguments
rettype functioname(type arg1, ..., type argn ???LS_DC) <-- a funciton with
arguments
Calls to such functions should look like this:
functionname(???LS_C) <-- a function with no arguments
functionname(arg1, ..., argn ???LS_CC) <-- a function with arguments
LS stands for 'Local Storage', _C stands for Call and _CC stands for Call
Comma, _D stands for Declaration and _DC stands for Declaration Comma.
Note that there's NO comma between the last argument and ???LS_DC or ???LS_CC.
If you do not pass the structure as an argument you can always fetch it by
using the appropriate ???LS_FETCH() macros within a functions variable
declarations.
In general, every module that makes use of globals should use this approach
if it plans to be thread safe.
[4] Generalized INI support
The code comes to solve several issues:
a. The ugly long block of code in main.c that reads values from the
cfg_hash into php3_ini.
b. Get rid of php3_ini. The performance penalty of copying it around all
the time in the Apache module probably wasn't too high, but
psychologically, it annoyed me :)
c. Get rid of the ugly code in mod_php4.c, that also reads values from
Apache directives and puts them into the php3_ini structure.
d. Generalize all the code so that you only have to add an entry in one
single place and get it automatically supported in php3.ini, Apache, Win32
registry, runtime function ini_get() and ini_alter() and any future method
we might have.
e. Allow users to easily override *ANY* php3.ini value, except for ones
they're not supposed to, of course.
I'm happy to say that I think I pretty much reached all goals. php_ini.c
implements a mechanism that lets you add your INI entry in a single place,
with a default value in case there's no php3.ini value. What you get by
using this mechanism:
1. Automatic initialization from php3.ini if available, or from the
default value if not.
2. Automatic support in ini_alter(). That means a user can change the
value for this INI entry at runtime, without you having to add in a single
line of code, and definitely no additional function (for example, in PHP3,
we had to add in special dedicated functions, like
set_magic_quotes_runtime() or the likes - no need for that anymore).
3. Automatic support in Apache .conf files.
4. No need for a global php3_ini-like variable that'll store all that
info. You can directly access each INI entry by name, in runtime. 'Sure,
that's not revolutionary, it's just slow' is probably what some of you
think - which is true, but, you can also register a callback function that
is called each time your INI entry is changed, if you wish to store it in a
cached location for intensive use.
5. Ability to access the current active value for a given INI entry, and
the 'master' value.
Of course, (2) and (3) are only applicable in some cases. Some entries
shouldn't be overriden by users in runtime or through Apache .conf files -
you can, of course, mark them as such.
So, enough hype, how does it work.
Essentially:
static PHP_INI_MH(OnChangeBar); /* declare a message handler for a change
in "bar" */
PHP_INI_BEGIN()
PHP_INI_ENTRY("foo", "1", PHP_INI_ALL, NULL, NULL)
PHP_INI_ENTRY("bar", "bah", PHP_INI_SYSTEM, OnChangeBar, NULL)
PHP_INI_END()
static PHP_INI_MH(OnChangeBar)
{
a_global_var_for_bar = new_value;
return SUCCESS;
}
int whatever_minit(INIT_FUNC_ARGS)
{
...
REGISTER_INI_ENTRIES();
...
}
int whatever_mshutdown(SHUTDOWN_FUNC_ARGS)
{
...
UNREGISTER_INI_ENTRIES();
...
}
and that's it. Here's what it does. As you can probably guess, this code
registers two INI entries - "foo" and "bar". They're given defaults "1"
and "bah" respectively - note that all defaults are always given as
strings. That doesn't reduce your ability to use integer values, simply
specify them as strings. "foo" is marked so that it can be changed by
anyone at any time (PHP_INI_ALL), whereas "bar" is marked so it can be
changed only at startup in the php3.ini only, presumably, by the system
administrator (PHP_INI_SYSTEM).
When "foo" changes, no function is called. Access to it is done using the
macros INI_INT("foo"), INI_FLT("foo") or INI_STR("foo"), which return a
long, double or char * respectively (strings that are returned aren't
duplicated - if they're manipulated, you must duplicate them first). You
can also access the original value (the 'master' value, in case one of them
was overriden by a user) using another pair of macros:
INI_ORIG_INT("foo"), INI_ORIG_FLT("foo") and INI_ORIG_STR("foo").
When "bar" changes, a special message handler is called, OnBarChange().
Always declare those message handlers using PHP_INI_MH(), as they might
change in the future. Message handlers are called as soon as an ini entry
initializes or changes, and allow you to cache a certain INI value in a
quick C structure. In this example, whenever "bar" changes, the new value
is stored in a_global_var_for_bar, which is a global char * pointer,
quickly accessible from other functions. Things get a bit more complicated
when you want to implement a thread-safe module, but it's doable as well.
Message handlers may return SUCCESS to acknowledge the new value, or
FAILURE to reject it. That enables you to reject invalid values for some
INI entries if you want. Finally, you can have a pointer passed to your
message handler - that's the fifth argument to PHP_INI_ENTRY(). It is
passed as mh_arg to the message handler.
Remember that for certain values, there's really no reason to mess with a
callback function. A perfect example for this are the syntax highlight
colors, which no longer have a dedicated global C slot that stores them,
but instead, are fetched from the php_ini hash on demand.
"As always", for a perfect working example of this mechanism, consult
functions/mysql.c. This module uses the new INI entry mechanism, and was
also converted to be thread safe in general, and in its php_ini support in
particular. Converting your modules to look like this for thread safety
isn't a bad idea (not necessarily now, but in the long run).

-----------------
1. Function Prototype
All functions look like this:
PHP_FUNCTION(foo) {
}
Even if your function doesn't take any arguments, this is how it is
called.
-----------------
2. Function Arguments
Arguments are always of type pval. This type contains a union which
has the actual type of the argument. So, if your function takes two
arguments, you would do something like the following at the top of your
function:
pval *arg1, *arg2;
if (ARG_COUNT(ht) != 2 || getParameters(ht,2,&arg1,&arg2)==FAILURE) {
WRONG_PARAM_COUNT;
}
NOTE: Arguments can be passed either by value or by reference. In both
cases you will need to pass &(pval *) to getParameters. If you want to
check if the n'th parameter was sent to you by reference or not, you can
use the function, ParameterPassedByReference(ht,n). It will return either
1 or 0.
When you change any of the passed parameters, whether they are sent by
reference or by value, you can either start over with the parameter by
calling pval_destructor on it, or if it's an ARRAY you want to add to,
you can use functions similar to the ones in internal_functions.h which
manipulate return_value as an ARRAY.
Also if you change a parameter to IS_STRING make sure you first assign
the new estrdup'ed string and the string length, and only later change the
type to IS_STRING. If you change the string of a parameter which already
IS_STRING or IS_ARRAY you should run pval_destructor on it first.
-----------------
3. Variable number of function arguments
A function can take a variable number of arguments. If your function can
take either 2 or 3 arguments, use the following:
pval *arg1, *arg2, *arg3;
int arg_count = ARG_COUNT(ht);
if (arg_count<2 || arg_count>3 ||
getParameters(ht,arg_count,&arg1,&arg2,&arg3)==FAILURE) {
WRONG_PARAM_COUNT;
}
------------------
4. Using the function arguments
The type of each argument is stored in the pval type field:
This type can be any of the following:
IS_STRING String
IS_DOUBLE Double-precision floating point
IS_LONG Long
IS_ARRAY Array
IS_EMPTY ??
IS_USER_FUNCTION ??
IS_INTERNAL_FUNCTION ?? (if some of these cannot be passed to a
function - delete)
IS_CLASS ??
IS_OBJECT ??
If you get an argument of one type and would like to use it as another,
or if you just want to force the argument to be of a certain type, you
can use one of the following conversion functions:
convert_to_long(arg1);
convert_to_double(arg1);
convert_to_string(arg1);
convert_to_boolean_long(arg1); If the string is "" or "0" it
becomes 0, 1 otherwise
convert_string_to_number(arg1); Converts string to either LONG or
DOUBLE depending on string
These function all do in-place conversion. They do not return anything.
The actual argument is stored in a union.
For type IS_STRING, use arg1->value.str.val
IS_LONG arg1->value.lval
IS_DOUBLE arg1->value.dval
-------------------
5. Memory management in functions
Any memory needed by a function should be allocated with either emalloc()
or estrdup(). These are memory handling abstraction functions that look
and smell like the normal malloc() and strdup() functions. Memory should
be freed with efree().
There are two kinds of memory in this program. Memory which is returned
to the parser in a variable and memory which you need for temporary
storage in your internal function. When you assign a string to a
variable which is returned to the parser you need to make sure you first
allocate the memory with either emalloc or estrdup. This memory
should NEVER be freed by you, unless you later, in the same function
overwrite your original assignment (this kind of programming practice is
not good though).
For any temporary/permanent memory you need in your functions/library you
should use the three emalloc(), estrdup(), and efree() functions. They
behave EXACTLY like their counterpart functions. Anything you emalloc()
or estrdup() you have to efree() at some point or another, unless it's
supposed to stick around until the end of the program, otherwise there
will be a memory leak. The meaning of "the functions behave exactly like
their counterparts" is if you efree() something which was not
emalloc()'ed nor estrdup()'ed you might get a segmentation fault. So
please take care and free all of your wasted memory. One of the biggest
improvements in PHP 3.0 will hopefully be the memory management.
If you compile with "-DDEBUG", PHP3 will print out a list of all
memory that was allocated using emalloc() and estrdup() but never
freed with efree() when it is done running the specified script.
-------------------
6. Setting variables in the symbol table
A number of macros are available which make it easier to set a variable
in the symbol table:
SET_VAR_STRING(name,value) **
SET_VAR_DOUBLE(name,value)
SET_VAR_LONG(name,value)
** Be careful here. The value part must be malloc'ed manually because
the memory management code will try to free this pointer later. Do
not pass statically allocated memory into a SET_VAR_STRING
Symbol tables in PHP 3.0 are implemented as hash tables. At any given time,
&symbol_table is a pointer to the 'main' symbol table, and active_symbol_table
points to the currently active symbol table (these may be identical like in
startup, or different, if you're inside a function).
The following examples use 'active_symbol_table'. You should replace it with
&symbol_table if you specifically want to work with the 'main' symbol table.
Also, the same funcions may be applied to arrays, as explained below.
* To check whether a variable named $foo already exists in a symbol table:
if (hash_exists(active_symbol_table,"foo",sizeof("foo"))) { exists... }
else { doesn't exist }
* If you also need to get the type of the variable, you can use:
hash_find(active_symbol_table,"foo",sizeof("foo"),&pvalue);
check(pvalue.type);
Arrays in PHP 3.0 are implemented using the same hashtables as symbol tables.
This means the two above functions can also be used to check variables
inside arrays.
If you want to define a new array in a symbol table, you should do this:
1. Possibly check it exists and abort, using hash_exists()
or hash_find().
2. Code:
pval arr;
if (array_init(&arr) == FAILURE) { failed... };
hash_update(active_symbol_table,"foo",sizeof("foo"),&arr,sizeof(pval),NULL);
This code declares a new array, named $foo, in the active symbol table.
This array is empty.
Here's how to add new entries to it:
pval entry;
entry.type = IS_LONG;
entry.value.lval = 5;
hash_update(arr.value.ht,"bar",sizeof("bar"),&entry,sizeof(pval),NULL); /* defines $foo["bar"] = 5 */
hash_index_update(arr.value.ht,7,&entry,sizeof(pval),NULL); /* defines $foo[7] = 5 */
hash_next_index_insert(arr.value.ht,&entry,sizeof(pval),NULL); /* defines the next free place in $foo[],
* $foo[8], to be 5 (works like php2)
*/
If you'd like to modify a value that you inserted to a hash, you must first retreive it from the hash. To
prevent that overhead, you can supply a pval ** to the hash add function, and it'll be updated with the
pval * address of the inserted element inside the hash. If that value is NULL (like in all of the
above examples) - that parameter is ignored.
hash_next_index_insert() works more or less using the same logic
"$foo[] = bar;" works in PHP 2.0.
If you are building an array to return from a function, you can initialize
the array just like above by doing:
if (array_init(return_value) == FAILURE) { failed...; }
and then adding values with the helper functions:
add_next_index_long(return_value,long_value);
add_next_index_double(return_value,double_value);
add_next_index_string(return_value,estrdup(string_value));
Of course, if the adding isn't done right after the array
initialization, you'd probably have to look for the array first:
pval *arr;
if (hash_find(active_symbol_table,"foo",sizeof("foo"),(void **)&arr)==FAILURE) { can't find... }
else { use arr->value.ht... }
Note that hash_find receives a pointer to a pval pointer, and
not a pval pointer.
Just about any hash function returns SUCCESS or FAILURE (except for
hash_exists() that returns a boolean truth value).
-------------------
7. Returning 'simple' values from functions (integers, floats or strings)
A number of macros are available to make it easier to return things from
functions:
These set the return value and return from the function:
RETURN_FALSE
RETURN_TRUE
RETURN_LONG(l)
RETURN_STRING(s,dup) If dup is true, duplicates the string
RETURN_STRINGL(s,l,dup) Return string (s) specifying length (l).
RETURN_DOUBLE(d)
These only set the return value:
RETVAL_FALSE
RETVAL_TRUE
RETVAL_LONG(l)
RETVAL_STRING(s,dup) If dup is true, duplicates the string
RETVAL_STRINGL(s,l,dup) Return string (s) specifying length (l).
RETVAL_DOUBLE(d)
The string macros above will all estrdup() the passed 's' argument,
so you can safely free the argument after calling the macro, or
alternatively use statically allocated memory.
If your function returns boolean success/error responses, always use
RETURN_TRUE and RETURN_FALSE respectively.
-------------------
8. Returning 'complex' values from functions (arrays or objects)
Your function can also return a complex data type such as an object
or an array.
Returning an object:
1. Call object_init(return_value).
2. Fill it up with values:
add_property_long(return_value,property_name,l) Add a property named 'property_name', of type long, equals to 'l'
add_property_double(return_value,property_name,d) Same, only a double
add_property_string(return_value,property_name,str) Same, only a string
add_property_stringl(return_value,property_name,str,l) Add a property named 'property_name', of type string, string is 'str' with length 'l'
3. Possibly, register functions for this object. In order to
obtain values from the object, the function would have to fetch
"this" from the active_symbol_table. Its type should be IS_OBJECT,
and it's basically a regular hash table (i.e., you can use regular
hash functions on .value.ht). The actual registration of the
function can be done using:
add_method(return_value,function_name,function_ptr)
Returning an array:
1. Call array_init(return_value).
2. Fill it up with values:
add_assoc_long(return_value,key,l) add associative entry with key 'key' and long value 'l'
add_assoc_double(return_value,key,d)
add_assoc_string(return_value,key,str)
add_assoc_stringl(return_value,key,str,length) specify the string length
add_index_long(return_value,index,l) add entry in index 'index' with long value 'l'
add_index_double(return_value,index,d)
add_index_string(return_value,index,str)
add_index_stringl(return_value,index,str,length) specify the string length
add_next_index_long(return_value,l) add an array entry in the next free offset with long value 'l'
add_next_index_double(return_value,d)
add_next_index_string(return_value,str)
add_next_index_stringl(return_value,str,length) specify the string length
-------------------
9. Using the resource list
PHP 3.0 has a standard way of dealing with various types of resources,
that replaces all of the local linked lists in PHP 2.0.
Available functions:
php3_list_insert(ptr, type) returns the 'id' of the newly inserted resource
php3_list_delete(id) delete the resource with the specified id
php3_list_find(id,*type) returns the pointer of the resource with the specified id, updates 'type' to the resource's type
Typically, these functions are used for SQL drivers but they can be
used for anything else, and are used, for instance, for maintaining
file descriptors.
Typical list code would look like this:
Adding a new resource:
RESOURCE *resource;
...allocate memory for resource and acquire resource...
/* add a new resource to the list */
return_value->value.lval = php3_list_insert((void *) resource, LE_RESOURCE_TYPE);
return_value->type = IS_LONG;
Using an existing resource:
pval *resource_id;
RESOURCE *resource;
int type;
convert_to_long(resource_id);
resource = php3_list_find(resource_id->value.lval, &type);
if (type != LE_RESOURCE_TYPE) {
php3_error(E_WARNING,"resource index %d has the wrong type",resource_id->value.lval);
RETURN_FALSE;
}
...use resource...
Deleting an existing resource:
pval *resource_id;
RESOURCE *resource;
int type;
convert_to_long(resource_id);
php3_list_delete(resource_id->value.lval);
The resource types should be registered in php3_list.h, in enum
list_entry_type. In addition, one should add shutdown code for any
new resource type defined, in list.c's list_entry_destructor() (even if
you don't have anything to do on shutdown, you must add an empty case).
-------------------
10. Using the persistent resource table
PHP 3.0 has a standard way of storing persistent resources (i.e.,
resources that are kept in between hits). The first module to use
this feature was the MySQL module, and mSQL followed it, so one can
get the general impression of how a persistent resource should be
used by reading mysql.c. The functions you should look at are:
php3_mysql_do_connect()
php3_mysql_connect()
php3_mysql_pconnect()
The general idea of persistence modules is this:
1. Code all of your module to work with the regular resource list
mentioned in section (9).
2. Code extra connect functions that check if the resource already
exists in the persistent resource list. If it does, register it
as in the regular resource list as a pointer to the persistent
resource list (because of 1., the rest of the code
should work immediately). If it doesn't, then create it, add it
to the persistent resource list AND add a pointer to it from the
regular resource list, so all of the code would work since it's
in the regular resource list, but on the next connect, the
resource would be found in the persistent resource list and be
used without having to recreate it.
You should register these resources with a different type (e.g.
LE_MYSQL_LINK for non-persistent link and LE_MYSQL_PLINK for
a persistent link).
If you read mysql.c, you'll notice that except for the more complex
connect function, nothing in the rest of the module has to be changed.
The very same interface exists for the regular resource list and the
persistent resource list, only 'list' is replaced with 'plist':
php3_plist_insert(ptr, type) returns the 'id' of the newly inserted resource
php3_plist_delete(id) delete the resource with the specified id
php3_plist_find(id,*type) returns the pointer of the resource with the specified id, updates 'type' to the resource's type
However, it's more than likely that these functions would prove
to be useless for you when trying to implement a persistent module.
Typically, one would want to use the fact that the persistent resource
list is really a hash table. For instance, in the MySQL/mSQL modules,
when there's a pconnect() call (persistent connect), the function
builds a string out of the host/user/passwd that were passed to the
function, and hashes the SQL link with this string as a key. The next
time someone calls a pconnect() with the same host/user/passwd, the
same key would be generated, and the function would find the SQL link
in the persistent list.
Until further documented, you should look at mysql.c or msql.c to
see how one should use the plist's hash table abilities.
One important thing to note: resources going into the persistent
resource list must *NOT* be allocated with PHP's memory manager, i.e.,
they should NOT be created with emalloc(), estrdup(), etc. Rather,
one should use the regular malloc(), strdup(), etc. The reason for
this is simple - at the end of the request (end of the hit), every
memory chunk that was allocated using PHP's memory manager is deleted.
Since the persistent list isn't supposed to be erased at the end
of a request, one mustn't use PHP's memory manager for allocating
resources that go to it.
Shutting down persistent resources:
When you register resource that's going to be in the persistent list,
you should add destructors to it both in the non-persistent list
and in the persistent list.
The destructor in the non-persistent list destructor shouldn't do anything.
The one in the persistent list destructor should properly free any
resources obtained by that type (e.g. memory, SQL links, etc). Just like
with the non-persistent resources, you *MUST* add destructors for every
resource, even it requires no destructotion and the destructor would
be empty.
Remember, since emalloc() and friends aren't to be used in conjunction
with the persistent list, you mustn't use efree() here either.
-------------------
11. Adding runtime configuration directives
Many of the features of PHP3 can be configured at runtime. These
configuration directives can appear in either the designated php3.ini
file, or in the case of the Apache module version in the Apache .conf
files. The advantage of having them in the Apache .conf files is that
they can be configured on a per-directory basis. This means that one
directory may have a certain safemodeexecdir for example, while another
directory may have another. This configuration granularity is especially
handy when a server supports multiple virtual hosts.
The steps required to add a new directive:
1. Add directive to php3_ini_structure struct in mod_php4.h.
2. In main.c, edit the php3_module_startup function and add the
appropriate cfg_get_string() or cfg_get_long() call.
3. Add the directive, restrictions and a comment to the php3_commands
structure in mod_php4.c. Note the restrictions part. RSRC_CONF are
directives that can only be present in the actual Apache .conf files.
Any OR_OPTIONS directives can be present anywhere, include normal
.htaccess files.
4. In either php3take1handler() or php3flaghandler() add the appropriate
entry for your directive.
5. In the configuration section of the _php3_info() function in
functions/info.c you need to add your new directive.
6. And last, you of course have to use your new directive somewhere.
It will be addressable as php3_ini.directive

GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts
as the successor of the GNU Library Public License, version 2, hence
the version number 2.1.]
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it. You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations
below.
When we speak of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.
To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that
there is no warranty for the free library. Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.
^L
Finally, software patents pose a constant threat to the existence of
any free program. We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder. Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License. This license, the GNU Lesser
General Public License, applies to certain designated libraries, and
is quite different from the ordinary General Public License. We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.
When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library. The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom. The Lesser General
Public License permits more lax criteria for linking other code with
the library.
We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License. It also provides other free software developers Less
of an advantage over competing non-free programs. These disadvantages
are the reason we use the ordinary General Public License for many
libraries. However, the Lesser license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it
becomes
a de-facto standard. To achieve this, non-free programs must be
allowed to use the library. A more frequent case is that a free
library does the same job as widely used non-free libraries. In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software. For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.
Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.
^L
GNU LESSER GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License").
Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control
compilation
and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
^L
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library". Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
^L
6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (1) uses at run time a
copy of the library already present on the user's computer system,
rather than copying library functions into the executable, and (2)
will operate properly with a modified version of the library, if
the user installs one, as long as the modified version is
interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
e) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
^L
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with
this License.
^L
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply, and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License
may add an explicit geographical distribution limitation excluding those
countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
^L
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
^L
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms
of the ordinary General Public License).
To apply these terms, attach the following notices to the library.
It is safest to attach them to the start of each source file to most
effectively convey the exclusion of warranty; and each file should
have at least the "copyright" line and a pointer to where the full
notice is found.
<one line to give the library's name and a brief idea of what it
does.>
Copyright (C) <year> <name of author>
This library is free software; you can redistribute it and/or
modify it under the terms of the GNU Lesser General Public
License as published by the Free Software Foundation; either
version 2 of the License, or (at your option) any later version.
This library is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
Lesser General Public License for more details.
You should have received a copy of the GNU Lesser General Public
License along with this library; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper
mail.
You should also get your employer (if you work as a programmer) or
your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
library `Frob' (a library for tweaking knobs) written by James
Random Hacker.

BCMATH FAQ:
1) Why BCMATH?
The math routines of GNU bc become more generally useful in a
library form. By separating the BCMATH library from GNU bc,
GNU bc can be under the GPL and BCMATH can be under the LGPL.
2) Why BCMATH when GMP exists?
GMP has "integers" (no digits after a decimal), "rational numbers"
(stored as 2 integers) and "floats". None of these will correctly
represent a POSIX BC number. Floats are the closest, but will not
behave correctly for many computations. For example, BC numbers have
a "scale" that represent the number of digits to represent after the
decimal point. The multiplying two of these numbers requires one to
calculate an exact number of digits after the decimal point regardless
of the number of digits in the integer part. GMP floats have a
"fixed, but arbitrary" mantissa and so multiplying two floats will end
up dropping digits BC must calculate.

This is bcmath, a library of arbitrary precision math routines.
These routines, in a different form, are the routines that to
the arbitrary precision calculations for GNU bc and GNU dc.
This library is provided to make these routines useful in a
larger context with less restrictions on the use of them.
These routines do not duplicate functionality of the GNU gmp
library. gmp is similar, but the actual computation is different.
