+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.
+This is an initial version - it'll most probably grow as time passes.
+
+
+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. _php3_addslashes())
+
+[5] Use php3_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.
+
+
+Naming Conventions
+------------------
+
+[1] Function names for user functions implementation should be prefixed with
+    "php3_", and followed by a word or an underscore-delimited list of words,
+    in lowercase letters, that describes the function.
+
+[2] Function names used by user functions implementations should be prefixed
+    with "_php3_", 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'.
+    
+[3] 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++) ...).
+
+[4] Variable names should be in lowercase;  Use underscores to seperate
+    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 she's 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 decleration
+    syntax.
+    
+[3] Be generous with whitespace and braces.  Always prefer
+    if (foo) {
+		bar;
+	}
+	to
+	if(foo)bar;
+	
+    Keep one empty line between the variable decleration 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.
+
+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)
+   Return the absolute value of the number */
+void php3_abs(INTERNAL_FUNCTION_PARAMETERS) {
+   ...
+}
+/* }}} */
+
+The {{{ symbols are the default folding symbols for the folding mode in
+Emacs.  vim will soon have support for folding as well.  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]]])
+
+And yes, please keep everything on a single line, even if that line is massive.
+

+December 24 1998, Version 3.0.6
+- Fix GetImageSize() to work with non-standard jpg images
+- Add Mersenne Twister functions (mt_rand, mt_srand, etc)
+- Add str_replace() function
+- Add chunk_split() function
+- Fixed a bug in the memory limit code, in cases where $php_errormsg was
+  also used.
+- Add iptcparse() function
+- Adobe FDF supported
+- getallheaders() NULL string fix <michale@utko.fee.vutbr.cz>
+- Add all configuration directives to phpinfo() page
+- Functions pack() and unpack() rewritten to be binary and buffer overrun
+  safe and behave like the Perl functions for all implemented format codes.
+- Ensured that msql_error() will not return error messages generated by
+  previously-run scripts.
+- Add base_convert() function
+- Make sprintf() and printf() output binary safe
+- Made gzgetc binary safe
+- Add convert_cyr_string() and quoted_printable_decode() functions
+- Fix ldap_free_result() core dump bug
+- Add support for current OpenLDAP-2.0-devel library
+- Add php3_asp_tags directive so it can be set from Apache config files
+- Added UTF-8 support in the XML extension
+- Make rand(min,max) safer on older platforms where the low-order bits have 
+  short cycles.
+- Added new pdf (Portable Document Format) module
+- Added an XML parsing extension using James Clark's "expat" library
+- Optimized parts of the token cache code.
+- Terminate on out-of-memory errors.  Until now, PHP could crash in out of
+  memory situations (clean-up, no real effect).
+- Unterminated comments in include files were being reported with the wrong line
+  number.  Fixed.
+- Added ImageCopy() and ImageColorDeallocate(). ImageCopy() is about
+  20% faster than ImageCopyResized(). ImageColorDeallocate() marks
+  palette entries free for reuse (by <mka@satama.com>).
+- In the CGI version, it was impossible to access resources (e.g. SQL links,
+  images) from user-defined shutdown functions.  Fixed.
+- Added optional third parameter to strpos() to specify the offset to
+  start searching from.
+- Fixed a crash bug in unset() when unsetting illegal variables (rare).
+- Made ImageInterlace and ImageTransparentColor parameters optional, and made
+  them return the current/new settings.
+- Optimized GetImageSize() <thies@digicol.de>.
+- Made odbc_autocommit() without args return status
+- Added connect workaround for OpenLink ODBC
+- Added minimal InterBase support. Tested only on 4.0 & Linux.
+- Fixed some memory leaks and bogus error messages in the URL handler of
+  the various file open functions.  Should only affect error handling
+  in bad URLs.
+
+October 5 1998 Version 3.0.5
+- mysql_field_flags now reports all MySQL flags and the result is suitable
+  for automatic parsing. Compatibility warning: The result format has
+  changed. If you have scripts parsing the result of this function, you
+  may need to adapt them.
+- Made nl2br() binary safe (not that it's of much use).
+- Fixed a bug in the API function getThis().  It affected mostly the dir
+  functions, if nested within objects.
+- Fixed a problem in require() in conjunction with switch(), and in some other
+  cases.  Also fixed an identical problem with the call_user_function() API
+  function.
+- Removed -lpthread when compiling with MySQL support.  It caused various
+  serious problems when compiled into Apache.
+- Add serialize() and unserialize() functions from jkl@njet.net
+- Fix in_addr_t check for systems with in_addr_t in netinet/in.h
+- Add atan2() function
+
+September 22 1998 Version 3.0.4
+- Added uksort() - array key sort using a user defined comparison function.
+- Added 'j' support to date() - generates the day of the month, without
+  possible leading zeros.
+- Added support for multiple crypt() encryptions if the system supports it
+- Added optional support for ASP-style <% %> and <%= tags
+- Fixed data loss problems with very large numeric array indices on 64-bit
+  platforms (e.g. DEC UNIX).
+- 2 cursor_type parameters for ifx_query() and ifx_prepare changed
+  to 1 (bitmask). Added a few constants for use in Informix module.
+- Added php3.ini option ifx.charasvarchar. If set, trailing blanks
+  are stripped from fixed-length char columns. (Makes life easier
+  for people using Informix SE.)
+- Static SNMP module which compiles with ucd-snmp 3.5.2
+- fixed imap_header & header_info from crashing when a header line
+  is > 1024 characters.
+- Added patch for rfc822_parse_adr to return an array of objects instead 
+  of a single object. 
+- Informix Online 7.x & SE 7.x support now fairly complete and stable
+- Add dbase_get_record_with_names() function
+- Added a special case for open_basedir. When open_basedir is set to "."
+  the directory in which the script is stored will be used as basedir.
+- Include alloca.c in the distribution for platforms without alloca().
+- Improved stripping of URL passwords from error messages - the length of the
+  username/password isn't obvious now, and all protocols are handled properly
+  (most importantly, http).
+- Copying objects that had member functions with static variables produced
+  undetermined results.  Fixed.
+- Added function lstat() and cleaned up the status functions,
+  added tests for file status functions (this may break on some plattforms)
+- Fixed is_link() - it was returning always false.
+- Fixed apache_note() - it was corrupting memory.
+- New Function.  void get_meta_tags(string filename);  Parses filename until
+  closing head tag and turns all meta tags into variables prefixed with 'meta_'.
+  The below meta tag would produce $meta_test="some string here"
+	<meta name="test" content="some string here">
+- Generalized some internal functions in order to better support calling
+  user-level functions from C code.  Fixes a few sporadic problems related
+  to constructors inside eval() and more.
+- Fixed an endless loop in explode(), strstr() and strpos() in case of an
+  invalid empty delimiter.
+- rand() now accepts two optional arguments, which denote the requested range
+  of the generated number.  E.g., rand(3,7) would generate a random number
+  between 3 and 7.
+- Added M_PI constant.
+- Added deg2rad() and rad2deg() for converting radians<->degrees.
+- ImageArc() misbehaved when given negative angles, fixed.
+- Fixed a bug in ereg() that may have caused buglets under some circumstances.
+- Added imap_status
+- Shutdown functions, registered via register_shutdown_function(), could never
+  generate output in the Apache module version.  Fixed.
+- Brought IMAP docs into sync with acutal imap code
+- imap_fetchstructure now takes in optional flags 
+- Fix potential core dumps in imap_append and imap_fetchtext_full
+- Fix problem in SetCookie() function related to long cookies
+- Add uasort() function to go along with usort (like sort() and asort())
+- Add port number to Host header as per section 14.23 of the HTTP 1.1 RFC
+- Fix imap_reopen to only take 2 arguments with an optional 3rd flags arg
+- Add optional 2nd argument to imap_close
+- Add CL_EXPUNGE flag to imap_open() flags
+- Fix 4th arg on imap_append().  It was getting converted to a long by mistake.
+- Fix shutdown warning in the LDAP module
+- *COMPATIBILITY WARNING* imap_fetchstructure() "parametres" object and property
+  name changed to "parameters" to match the documentation and to be consistent
+  with the rest of the API.
+- Delete uploaded temporary files automatically at the end of a request
+- Add upload_max_filesize and correponsing php3_upload_max_filesize directive
+  to control the maximum size of an uploaded file.  Setting this to 0 would
+  completely eliminate file uploads.
+- Force $PHP_SELF to PATH_INFO value when running in CGI FORCE_CGI_REDIRECT mode
+- Add apache_lookup_uri() function which does an internal sub-request lookup
+  and returns an object containing the request_rec fields for the URI.  (Yes,
+  you have to be a bit of a gearhead to figure this one out)
+- Fix a few signed char problems causing functions like ucfirst() not to work
+  correctly with non-English charsets
+- md5() function not binary safe - fixed
+
+August 15 1998 Version 3.0.3
+- Changed the name of fopen_basedir to open_basedir, to be a little more
+  accurate about what it does.
+- Added Hyperwave module
+- Added config-option (php3_)enable_dl <on/off>. This enables/disables the
+  dl() function.  In safe-mode dl() is always disabled.
+- Auto-prepended files were crashing under some circumstances - fixed.
+- Win32 mail fixes provided by walton@nordicdms.com
+- Comparing between arrays and/or objects now generates a warning (it always
+  returns false, as it used to;  no comparison is made)
+- Fixed a bug in the syntax highlighting code, that made ending-double-quotes
+  appear twice under certain circumstances.
+- Fix bug in filetype() function related to symlinks
+- Started integrating Informix SE support to PHP configure/makefile setup.
+- gdttf roundoff fixes from ellson@lucent.com
+- Added initial Informix SE support files from Danny Heijl - This code still
+  needs to be integrated into the PHP configure/makefile setup and the code
+  itself needs more work.
+- return in the global scope now terminates the execution of the current file.
+- Added the ability to register shutdown function(s), via
+  register_shutdown_function($function_name).
+- Clean up const warnings
+- Add write support to ftp fopen wrappers
+- Add strspn() and strcspn() functions
+- On systems without strerror use Apache version if compiling as Apache module
+- The PHP start tag was being ignored under some circumstances - fixed.
+- The db, dbase and filepro functions are now Safe-Mode aware.
+- Added config-option (php3_)fopen_basedir <path>. This limits the directory-
+  tree scripts can open files in to <path>.
+- Fixed pg_loreadall that didn't always return all the contents in a PostgreSQL
+  large object. Also, doesn't pass through anything if method is HEAD.
+- configure fix to create target Apache module dir
+- Fix core dump in imageTTFtext() function
+- Added static IMAP support
+- Syntax highlighting was generating additional whitespace - fixed.
+- Added ucwords.  Works like ucfirst, but works on all words within a string.
+- Added array_walk() - apply user function to every element of an array
+- Added usort() - array sort that accepts a user defined comparison function!
+- Added the ability to call user-level functions and object methods on demand
+  from the C source using a completely generalized, slick API function.
+  Miracles do happen every once in a while.
+- Added constructors.  Don't even squeek about destructors! :) (we mean that)
+- Make pg_lowrite() binary safe
+- Fixed mod_charset option in ./setup
+- Fixed rewinddir() and dir()::rewind() under Win32 (they didn't work before).
+- Add Win32 COM support!  By-name referencing is supported using the IDispatch
+  interface (automation).  Available functions - COM_Load(), COM_Invoke(),
+  COM_PropGet() and COM_PropSet().
+  
+July 20 1998 Version 3.0.2a
+- Fix a quirk in the configuration file parser, the endless fountain of joy
+  and fun.

+- Made getdate() without args default to current time
+- Added ImageColorResolve() and some fixes to the freetype support.
+- Added strcasecmp()
+- Added error_prepend_string and error_append_string .ini and .conf directives
+  to make it possible to configure the look of error messages displayed by PHP
+  to some extent
+- Added E_ERROR, E_WARNING, E_NOTICE, E_PARSE and E_ALL constants, that can be
+  used in conjunction with error_reporting()
+  (e.g. error_reporting(E_ERROR|E_WARNING|E_NOTICE);
+- Fixed a crash problem with classes that contained function(s) with default
+  values.
+- Fixed a problem in the browscap module.  Browscap files weren't being read
+  properly.

+- Added constants for Ora_Bind()'s modes.
+- Renamed all hash_*() routines to _php3_hash_*() to avoid clashes with other
+  libraries.

+  and pg_fetch_object()
+- Fix a segmentation fault when calling invalid functions in certain
+  circumstances

+- Several fixes to the configuration file parser
+- LDAP fixes - fixed return values on several functions
+
+May 23 1998 Version 3.0RC5
+- The BC math library functions now compile in by default.
+- Fixed a bug in virtual() and other types of SSI's (e.g. <!--#exec).  Under
+  certain circumstances, this used to result in random problems.
+- Fixed a bug in virtual().  It was misbehaving if it was called before any
+  other output.
+- Added mysql.default_port, mysql.default_host, mysql.default_user and
+  mysql.default_password ini-file directives.
+- Improved handling of the MySQL default port.  It now honors /etc/services
+  and $MYSQL_TCP_PORT.
+- Fixed a crash in opening of broken ftp:// URLs, and improved error reporting
+  in opening of URLs.
+- Fixed several non-critical scanner issues with syntax highlighting mode and
+  the <script language=php> tag.
+- Fixed fseek on windows.  (windows only): fseek will not return proper results
+  on files opened as text mode.  PHP uses binary mode as the default for file

+  mode and use fseek on them!
+- Add strpos() function
+- Added zlib module, requires zlib >= 1.0.9
+- Improved the module API implementation.  Dynamic modules may now register
+  persistent resources (not that it makes much sense, but at least PHP
+  won't crash).  The API itself remains unchanged.
+- bcmod() wasn't always behaving like modulus should behave (it was behaving
+  exactly like GNU bc's % operator).  Fixed.
+- Changed the Sybase-DB module to always return strings, instead of auto-typing
+  result sets.  This was done for consistency with the other database modules,
+  and in order to avoid overflows due to the platform-dependant limitations
+  of the numeric data types of PHP.  You can turn compatability mode on using
+  the sybase.compatability_mode directive in the php3.ini file.
+- Fixed problems with the TINYINT field in the Sybase-CT module.
+- Applied some small speed optimizations to the Sybase-DB module querying code.
+- Added 'numeric' and 'type' properties to the object returned by
+  sybase_fetch_field().
+- The 'new' operator doesn't accept all expressions anymore.  Instead, it
+  accepts a class name, or a variable reference (scalar, array element, etc).
+- Add ora_numcols() function
+- Add ora_do() and ora_fetch_into() functions to Oracle driver
+- Add persistent connection support to Oracle driver
+- Make Oracle driver clean up open connections and open cursors automatically
+- Added fread() and fwrite() that properly handle binary data.
+- Add Ora_ColumnSize() to Oracle code
+- The string "0" means FALSE again.  This was done in order to maintain type
+  conversion consistency.
+- Added solid_fetch_prev() for fetching the previous result row from Solid.
+- Huge integers are now automatically converted to floating point numbers
+  (that have a wider range).
+- Floating point numbers are now displayed using scientific notation when
+  they're extremely big or extremely small.  The 'precision' php3.ini directive
+  no longer designates the number of decimal digits, but rather, the maximum
+  number of significant digits required.
+- Added support for scientific notation for floating point numbers (e.g. 1E7)
+  throughout the entire language.
+- Fixed a potential/probable memory corruption problem with HEAD request
+  handling.
+- Using un-encapsulated strings now generates a NOTICE-level warning
+  (e.g. $a = foo; instead of $a = "foo";)
+- Added defined("name") function to check if a certain constant is defined
+  or not.
+- Support new Apache mechanism for setting SERVER_SUBVERSION
+- Added PHP_OS and PHP_VERSION constants
+- Added the ability to define constants in runtime!  Constants are script-wide,
+  (there's no scope, once the constant is defined, it's valid everywhere).
+  Syntax is define("name", $value [, $case_insensitive]).  'name' can be any name
+  that is a valid variable name, *without* the $ prefix.  'value' can be
+  any *scalar* value.  If the optional 'case_insensitive' parameter is 1,
+  then the constant is created case-insensitive (the default is case
+  sensitive).  Note:  define() is currently *NOT* supported in preprocessed
+  scripts.
+- Added general support for constants.  The Syslog constants (e.g.
+  LOG_ERR, LOG_CRIT, etc.) should be accessed as constants from now on (that
+  is, without a $ prefix).  You can still set define_syslog_variables to On
+  in the php3.ini file if you want to define the various $ variables.  The
+  default for this directive in the php3.ini-dist file has been changed to
+  Off.
+- The configuration file path variable now expands . and .. into their
+  respective directories.  You can obtain the path of the php3.ini file
+  that was used by printing get_cfg_var("cfg_file_path").
+- Fixed a crash-recovery parser crash ($a=7; $a[3]+=5;)
+- Add gmmktime() function
+- Fixed a crash with implode() and empty arrays.
+- Fixed a bug that, under fairly rare circumstances, caused PHP not to
+  recognize if(), require() and other statements as statements, and
+  to complain about them as being unsupported functions.
+- Beautified php3.ini-dist and added more comments to it.  Also changed
+  the behavior of the configuration file parser to be brighter about
+  the various constants (TRUE/FALSE/ON/OFF etc).
+- Fixed a bug in openlog() - the specified device name was being mangled.
+- Memory leaks were sometimes reported erroneously - fixed.
+- Improved the convertor to handle some quirks of the PHP/FI 2 parser with
+  comments.
+- Fixed number_format() to properly handle negative numbers, and optimized it
+  a bit.
+- Fixed static variables inside class member functions.  Note that using such
+  static variables inside member functions usually defeats the purpose of
+  objects, so it is not recommended.
+- Fixed a bug in fpassthru() (the file was being closed twice).
+- Added strftime().
+- Add set_socket_blocking() function to control blocking on socket fd's
+- The sendmail_path in php3.ini was being ignored - fixed.
+- Fixed a bug with file upload, with files that contained the MIME boundary
+  inside them.
+- Fixed a bug with form variables of type array, with spaces in their
+  index (e.g. name="foo[bar bar]").
+- gd-1.3 autodetect and support
+- Year 2000 compliance is now togglable from the php3.ini file.  Setting PHP
+  to be y2k compliant effects the way it creates cookies, and means it'll
+  NOT work with many browsers out there that are not y2k compliant!  For
+  that reason, the default for this option is off.
+- safe mode / fix from monti@vesatec.com
+- Integrated the FreeType support in the GD extension.
+- Added --with-gd=DIR and --without-gd options to configure
+
+April 18 1998 Version 3.0 Release Candidate 4
+- Auto-prepended and auto-appended files were reporting the wrong filename
+  in errors and in __FILE__ - fixed.
+- Fix GPC problem related to mixed scalar and array vars with the same name
+- Made putenv() Apache-safe.  Environment variables may no longer leak in
+  between requests.
+- The trailing semicolon is no longer required in class declarations.
+- Fixed a memory leak in the (array) and (object) operators under certain
+  conditions.
+- <script> tags weren't working unless short tags were enabled - Fixed.
+- Fixed a bug in certain array indices that weren't treated as numbers
+  even though they looked like numbers (e.g. "10", "20").
+- Changes to support renamed API functions in Apache-1.3
+- Fixed the -p and -e command line switches
+- Fix a segfault when calling command line version without parameters

+  module builds.  See INSTALL file.
+ 
+March 30 1998 Version 3.0 Release Candidate 2
+- Changed the socket implementation under UNIX to not use FILE pointers, in
+  order to work around the buggy Solaris libc (and possibly buggy libc's
+  in other platforms).
+- Fixed a bug in min() and max() with certain arrays.
+- *WARNING* Move Apache 1.3 php3 file install to src/modules/php4 instead of 
+  src/modules/extra.  Make sure you change your AddModule line correctly
+  in your Apache Configuration file.  This change is to take advantage of 
+  new Apache-1.3 configuration mechanism which makes it easier to build an
+  Apache server with PHP automatically enabled.  It will also help building
+  a shared library module version of PHP soon.
+- Fixed a crash bug with auto-appended files.
+- Made --enable-discard-path work on all Unix servers #!/path/php CGI scripts 
+  should now work everywhere.  I have tested on Apache, WN and Netscape 2.0
+- Made $a["123"] and $a[123] be identical.  $a["0123"] is still different,
+  though.
+- Added 'precision' ini directive, to set the number of decimal digits
+  displayed for floating point numbers (default - 6).
+- Made integer/integer divisions evaluate to floating point numbers when
+  applicable (e.g., 5/2==2.5(float), but 4/2==2(int))
+- Get rid of reliance on tied streams and move all socket reads and writes
+  to recv/send calls
+- Cleaned up head.c a bit and fixed CGI SetCookie order problem
+- Changed default variable parsing order to Get-Cookie-Post (GPC)
+- Fixed setup so it has all configure options and defaults.
+- Added optional decimal point and thousands seperator to number_format()
+  e.g., number_format(1500,2,',','.') == 1.500,00
+- Fixed cgi bug in windows that prevented files from being parsed on many
+  systems and servers.
+
+March 23 1998 Version 3.0 Release Candidate
+- Added support for the Raima database (ALPHA)
+- Fixed a bug in persistent PostgreSQL links and the connection-string method.
+- Added EXTENSION_STATUS file, that specifies the stability and status of
+  every module in the distribution.
+- Added optional parameters to user functions with default values, variables
+  that are forced to be passed by reference and variables that can be
+  optionally passed by reference.  The ini file directive
+  'ignore_missing_userfunc_args' is no longer supported.
+- Added fhttpd support (by Alex Belits)
+- Improved performance by approximately 20-30%.
+- Added mysql_error(), mysql_errno() (if available) and msql_error().
+  Errors coming back from the database backend no longer issue warnings.
+  Instead, use these functions to retreive the error.
+- Patched count(), each(), prev(), next(), reset() and end() to work around
+  the implementation side effects of unset().  As far as the users are
+  concerned, this should be transparent now (even though it's slower now,
+  until it's thoroughly fixed in 3.1).
+- Added number_format().  number_format(2499,2)=='2,499.00'.
+- error_reporting() now sets the error reporting level to the supplied
+  argument, without any interpretations.
+- Fixed a lookahead parser bug that occured under rare circumstances.
+- Change the comparison operators to compare numeric strings as numbers.  If
+  you want to compare them as strings, you can use the new C-like strcmp()

+- Added Ora_ColumnName() and Ora_ColumnType()
+- Preliminary LONG and LONG RAW support in Oracle extension
+- Add \123 and \xAB style octal and hex escapes to "" and `` strings

+- Improved list() so that elements can be skipped, for example:
+  list($name,,,$realname) = explode(":",fgets($passwd_file));
+- Fixed a tiny bug in the hash initialization which caused excessive use of
+  memory. Report and fix by short@k332.feld.cvut.cz
+- Fixed strtolower() and strtoupper() to work with 8-bit chars

+  and didn't work with arrays.
+- Made [m,My]SQL create/drop database functions return success status
+- Fixed some memory leak/crash problems in the Adabas module
+- Added each() in order to allow for easy and correct array traversing.
+- Make Apache module version respect LOCALE setting
+- Add support for Apache 1.3b6+ ap_config.h file

+  names.
+- Fixed a possible crash and/or file descriptor leak
+- Fixed line number being off by one in #! shell style execution

+  which are refered to as objects.
+- Fixed several fields that were being incorrectly read in Sybase CT.
+- Fix Apache-1.3 related SIGHUP problem which was preventing php3.ini from 
+  getting re-read on a SIGHUP
+- *** WARNING *** Downwards incompatible change:  The plus operator (+) is not
+  longer overloaded as concatenation for strings.  Instead, it converts its
+  arguments to numbers and performs numeric addition.

+- Add arg_separator .ini directive so the '&' GET method separator can be
+  changed to ';' for example.  Corresponding php3_arg_separator Apache .conf
+  directive works as well.
+- Walked around an implementation side effect of switch().  <? switch(expr) { ?>
+  now works.
+- Added memory caching, resulting in a significant performance boost
+- Added support for for(): .. endfor; loops
+- Added a new predicate - empty($var).  Returns true if $var is not set,
+  or is FALSE.  Returns false otherwise.
+- Added is_integer() (same as is_long()) and is_real() (same as is_double()).
+- Added sizeof() as an alias to the count() function
+- Added --enable-force-cgi-redirect, to prevent the CGI from working if
+  someone directly accesses PHP not through Apache's CGI redirect
+  (off by default).
+- Fixed marking of deleted dBase records. Noticed by Simon Gornall
+  <simon@oyster.co.uk>.
+- Fixed fixed "%%" bug in [s]printf
+- Fixed a UMR (initialized memory read) in the Oracle code

+  dies).
+- Fixed a crash bug with StrongHold and secure pages
+- Fixed StrongHold installation
+- Optimized the function call sequence a bit.
+- Fixed Sybase/CT date/datetime/money fields work to correctly.
+- Fixed Apache module startup problems - php3_module_startup should only be

+- Fixed a file descriptor leak in the configuration parser.
+- Fixed a few buglets with syntax highlighting with certain language keywords
+- Added functions to control minimum severity level of Sybase messages to
+  display.
+- Added highlight_string() - behaves like highlight_file(), only instead
+  of highlighting a file, it syntax highlights the contents of its
+  argument.
+- Renamed show_source() to highlight_file().  show_source() is still
+  supported for downwards compatability.
+- Fixed a bug in class inheritence - member functions with upper case
+  letters in their names couldn't be redefined.
+- Made chown(), chgrp() and chmod() return TRUE/FALSE instead of 0/-1.

+  include path inadvertantly.
+- Fixed a (documented) bug in printf()/sprintf() with hard limited strings
+  and alignment (e.g. %-.20s).
+- Optimized several quoted string routines.
+- Added error_log ini directive to select where errors get logged when
+  log_errors is turned on or the error_log() function is used.
+- Added the ability to direct errors to log files instead of or in addition
+  to the script output.  Use the new display_errors and log_errors
+  php3.ini directives.
+- Made environment variables uneraseable by POST/GET/Cookie variables.
+- Fixed a bug in the elseif() construct.  The expression was being evaluated
+  even if a previous if/elseif already evaluated to true and got executed.

+- Made keywords be valid property names of objects.
+- Fixed a segfault bug when creating new objects of an unknown class.
+- Fixed a problem with the maximum execution time limit, that may have
+  prevented this feature from working on certain platforms.
+- PHP would now warn you with E_NOTICE about unknown escape characters,
+  e.g. "\f".  It would still be considered as a backslash followed by f,
+  but the proper way of writing this is "\\f" or '\f'.
+- Added support for ${...} inside encapsulated strings.  Supported:  ${foo},
+  ${foo[bar]}, ${foo[0]}, ${$foo[$bar]}, ${$foo->bar} and ${$foo}
+- Fixed a bug in automatic persistent link reconnect of the Sybase/DB module.
+  Thanks to Steve Willer for finding that 'stealth' bug!

+  from being properly decoded. (Thanks again to colins@infofind.com.)
+- Make dbase_get_record include a 'deleted' field that indicates whether
+  that record had been marked for deletion.
+- Fixed bug in dbase library that stomped on the deleted flag of the first
+  record in the file if it was set. (Thanks to colins@infofind.com.)
+- Fixed putenv() to not report a memory leak and possibly prevent a bug
+  from that memory being freed.
+- Added setlocale()

+- Changed pg_exec() to always return a result identifier on succees
+- Solid linking fixes (tries to find the right library)

+- Fixed http:// URL includes with no path specified send request for /.
+- Added GetAllHeaders() (Apache-only)
+- Added workaround that made the Image text functions 8-bit clean
+- Made snmp internally compilable for Win32 (not the unix one though),

+- Fixed compilation of syntax highlighting mode
+
+January 17 1998 Version 3.0b3

+- Fixed dbase.dll for Win32 to actualy load now.
+- Enhanced the convertor to recognize ?> as a php-close-block as well.
+- Fixed potential SetCookie() core dumps

+  changed.
+- Removed the flex optimization flags to reduce the size of the scanner
+- Added memory leak logging into apache log files (apache module only)

+- Added get_cfg_var() to enable checking cfg file directives from within
+  a script.

+  argument are no more evaluated as escape sequences.
+- Fixed a bug in the configuration file loader and safe mode.
+- Fixed a bug with configuration variables taken from the environment.
+- Added <script language=php> </script> as PHP open/close tags, to allow

+  rows (update, insert, etc).
+
+December 22 1997 Version 3.0b2
+- Changed variable type conversions that do not specify base to always use
+  base 10.  "010" is no more 8, it is 10.  Use intval ($x, 0) to get C-style
+  octal and hex numbers recognized.
+- Fixed a possible segfault bug in several functions, when using the concat
+  operator and possibly other operators/functions.
+- # is no longer accepted as a comment in php3.ini.  Use ; instead.

+- fixed mail() on windows, also fixed memory leaks in mail on windows
+- added sendmail_from to handle return route on windows
+- Changed the way the config file is searched.  The file name is now
+  php3.ini (hardcoded), and it'll be looked for in:  local directory, $PHPRC
+  and builtin path designated by ./configure under UNIX or Windows directory 
+  under Windows.
+- Fixed ereg_replace replacing empty matches and a one off buffer overflow
+- Fixed File upload on windows platform
+- Fixed a bug that caused 'HTTP/1.1 100 Continue' messages with 
+  Internet Explorer 4.0 and certain scripts that receive POST variables
+- Get/POST/Cookie data variables are from now *ALWAYS* strings.  If you want
+  to use them in integer/real context, you must explicitly change their types.
+  This was done in order to avoid possible loss of data when doing these
+  conversions automatically.
+- Variables named as keywords are now allowed (e.g. $function, $class, etc)
+- Fixed a problem with msql() and mysql() with NULL fields
+- Fixed a segfault bug with class declarations
+- Fixed bugs with FOR loops and include() from within eval()
+- Changed include() to be executed conditionally.  PHP-3.0 efficient
+  unconditional include is now require()
+
+December 08 1997 Version 3.0b1
+- Switched to public beta test phase
+- Generalized unset() and isset() to work on any type of variables, including
+  specific array indices or object properties (e.g., unset($a[4]) now works).

+  (for example, 'echo "Username:  $user->name"' now works)
+- Added arbitary precision math support (basic operations with
+  unlimited range numbers, and support for unlimited decimal digits)
+- Apache module can now handle preprocessed scripts (by using:
+	AddType application/x-httpd-php3-preprocessed .php3p
+  in the Apache configuration)

+- Computed field names in the Sybase/CT and Sybase/DB modules are now named
+  computed, computed1, computed2, ...

+- Made the regexp function automatically take arguments by reference
+  when necessary
+- Added builtin support for auto append and prepend in the parser level
+- Improved the Sybase/CT sybase_query().  Should be more stable now, and
+  hopefully work with a wider range of queries.  It's difficult to work
+  without docs, though, so it may still not be 100% right...
+- Changed error messages to show error type, file and line with bold
+- Added support for autoprepend and autoprepend
+- Added some more warning flags if gcc is used
+
+December 03 1997 Version 3.0a4
+- Improved the internal functions API - no need to explicitly pass
+  parameters by reference to internal functions that specifically
+  require them, e.g. sort(), ksort(), reset(), count(), etc.
+  This is *STILL* downwards compatible with the previous alphas,
+  in the sense that you can explicitly pass the arguments by reference
+  if you want to.
+- use srandom/random instead of srand/rand if available
+- Added [m,My]sql_listfields() for downwards compatability
+- -p now replaces .php3 extension with .php3p (otherwise it adds .php3p)
+- Added C++ style comments (// comment)

+- Added \0 back reference for full string match to *reg*_replace and
+  added backslash escaping to replace string
+- Fixed a few bugs in the Sybase DB-library module.
+- Added Sybase CT-library support.  It should be considered experimental.
+  Syntax is identical to the one of the DB-library.  Allows people to
+  connect to MS-SQL servers from Linux without having to pay for a
+  library!
+- Beautified phpinfo()
+- Add ImageColorClosest() and ImageColorExact() GD functions
+- Make all .ini directives work as Apache .conf directives as well
+- Added PHP2-like File() function with PHP3 URL support
+- Upgraded the Sybase interface.  It's practically MySQL compatible now!
+  Among other things, added sybase_fetch_array() and sybase_fetch_object().
+- Fixed problem in multi dimensional array handling and self modifying
+  operators (+=, -=, etc).
+- Safe Mode file open implementation
+- SVR3 portability problem fix
+
+November 23 1997 Version 3.0a3

+  (The default is to assume you want to do a base 10 conversion.)
+- Implemented SQL safe mode for MySQL
+- Read UploadTmpDir from php3.ini instead of apache conf files
+- Added mysql_fetch_object() and mysql_fetch_array()

+This is the ChangeLog from PHP3 as of Apr 12 1999. 
+
+Entries should be removed from this file, if you transfer changes
+over to PHP4.
+
+============================================================================
+
+?? 1999, Version 3.0.8
+- added Oracle-OCI8 persistent connections
+- fixed OCIDefineByName crash.
+- fixed some NULL-column related problems in OCI8-module.
+- Some Informix driver improvements.
+- PUT method support (mlemos@acm.org)
+- Fix parameter count problem in odbc_setoption()
+- Really fix implode() this time.  The fix in 3.0.7 was bogus
+- Make fgetss() slightly smarter
+- Add strip_tags() which uses the fgetss state-machine but acts on a string
+
+March 1 1999, Version 3.0.7
+- Added pdf_put_image and pdf_execute_image
+- Initial work on an ImageMagick module - doesn't do anything yet
+- Make configure script detect Netscape's LDAP SDK automagically
+- Fixed Oracle-OCI8 module for windows.
+- Add OCIRowCount function. (Number of affected rows for update-statements)
+- Add OCIDefineByName function.
+- Change the behaviour of open_basedir. It's now possible to supply more
+  than one directory. open_basedir paths from parent directories are now
+  automatically inherited.
+- fix rand() and mt_rand() to make the ranges work correctly
+- htmlspecialchars() and htmlentities() are now binary safe.
+- Add extract() function.
+- Oracle-OCI8 driver now supports BLOBS/CLOBS and IN/OUT binding of local php
+  variables.
+- Clean up apxs build
+- Add INSTALL.REDHAT file to walk RedHat users through the install
+- Added optional second argument to mysql_fetch_array();  MYSQL_ASSOC will
+  cause the resulting array to contain the associative indices only,
+  MYSQL_NUM will cause the array to contain the numeric indices only (like
+  mysql_fetch_row()) and MYSQL_BOTH would cause them both to be defined
+  (default).
+- Backport the Zend debugging memory manager into the PHP 3.0.x tree.
+- Add function_exists() function.
+- Add another version of WDDX module
+  (we need to pick a single implementation here)
+- Fixed includes for iODBC to support both the old and the new LGPL version
+- Fix implode() bug - When imploding an array that contained unset() elements
+  it wasn't correctly skipping past these
+- Add connection_status() function.  This returns the raw bitfield which
+  indicates whether the script terminated due to a user abort, a timeout
+  or normally.  Note that if ignore_user_abort is enabled, then both the
+  timeout state and the user abort state can be active
+- Add connection_timeout() function.  This one can be called in a shutdown
+  function to tell you if you got there because of a timeout
+- Add ignore_user_abort() function and .ini/.conf directive of same name
+- Fix connection abort detection code - It should now work reliably with
+  Apache.  Also added a user-level connection_aborted() function designed to
+  let people check whether the user aborted the connection in a user-level
+  shutdown function.
+- Add pfsockopen() function
+- Improvements in FreeType support: Macintosh fonts work, and non-antialiased
+  output is considerably cleaner  <mka@satama.com>
+- Fixed checkdate() function, range of valid years is now 0 to 32767
+- hw_insertdocument() returns object id now
+- Add pdf_open() warning in configure and documentation
+- Add diskfreespace() function
+- Added aspell support
+- Iptcparse would sometimes find a wrong tag.
+- Force var_dump() to output headers
+- Add optional 3th parameter to ora_fetchinto.
+- Serialize and var_dump no longer show array elements that
+  have been unset.
+- Add IptcEmbed() function (can replace an APP13-Marker in a JPEG file)
+- Add OCI8 module for Windows
+- Fix bug in pdf_close() function
+- Add WDDX support (see http://www.wddx.org for more info)
+- Add similar_text() function
+- Constructors of parent classes weren't accessible to derived classes (as
+  of 3.0.6).  Fixed.
+- Introduce simple regex compilation cache

+Installation Instructions for PHP 4.0
+-------------------------------------
+
+For the impatient here is a quick set of steps that will build PHP
+as an Apache module for Apache 1.3.0 with MySQL support.  A more verbose 
+explanation follows.
+
+
+QUICK INSTALL
+
+gunzip apache_1.3.x.tar.gz
+tar xvf apache_1.3.x.tar
+gunzip php-4.0.x.tar.gz
+tar xvf php-4.0.x.tar
+cd apache_1.3.x
+./configure --prefix=/www
+cd ../php-4.0.x
+./configure --with-mysql --with-apache=../apache_1.3.x --enable-track-vars
+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)
+cd ../php-4.0.x
+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
+
+Installing PHP can be done in four simple steps:
+
+1. Unpack your distribution file.  
+
+   You will have downloaded a file named something like php4xn.tar.gz.
+   Unzip this file with a command like: gunzip php4xn.tar.gz
+
+   Next you have to untar it with: tar -xvf php4xn.tar
+
+   This will create a php-4.0.x directory.  cd into this new directory.
+
+2. Configure PHP.
+
+   You now have to choose the options you would like.  There are quite
+   a few of them.  To see a list, type: ./configure --help
+
+   You can also use the supplied 'setup' script, which will ask you
+   a series of questions and automatically run the configure script
+   for you.
+
+   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.
+
+3. Compile and install the files.  Simply type: make install
+
+   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
+
+4. Setting up the server.
+   
+   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/srm.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.
+
+   When you are finished making changes to your srm.conf file, you can
+   start up your server.

+How to install PHP with the BCMath arbitrary precision math library?
+--------------------------------------------------------------------
+
+Due to license restrictions, the BC math library can no longer be distributed
+along with PHP.  The BC math library is distributed under the restrictive
+GNU Public License, and PHP is no longer distributed under that license, but
+under a less restrictive license, the PHP License.
+
+If you want to enable BC math support (recommended), all you have to do is
+simply download http://www.php.net/extra/number4.tar.gz, and untar it on the
+top level php4 directory.
+
+A typical way of doing this would be (assuming that you have lynx):
+cd ~/php4
+lynx -dump -source http://www.php.net/extra/number4.tar.gz | gzip -d | tar xvf -

+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.

+Improvements
+------------
+
+Zend was designed from the ground up for increased speed,
+reduced memory consumption and more reliable execution.  We dare
+say it meets all of these goals and does so pretty well.  Beyond
+that, there are several improvements in the language engine
+features:
+
+* References support.  $foo = &$a; would make $foo and $a be two
+  names to the same variable.  This works with arrays as well,
+  on either side;  e.g., $foo = &$a[7]; would make $foo and $a[7]
+  be two names to the same variable.  Changing one would change
+  the other and vice versa.
+* Object overloading support.  This feature allows various OO
+  libraries to use the OO notation of PHP to access their
+  functionality.  Right now, no use is made of that feature,
+  but we'd have a COM module ready by the time PHP 4.0 is released.
+  A CORBA module would probably follow.
+* include() and eval() are now functions, and not statements.
+  That means they return a value.  The default return value from
+  include() and eval() is 1, so that you can do if (include())
+  without further coding.  The return value may be changed by
+  returning a value from the global scope of the included file
+  or the evaluated string.  For example, if 'return 7;' is executed
+  in the global scope of foo.inc, include("foo.inc") would evaluate
+  to 7.
+* Automatic resource deallocation.  Several people have been bitten
+  by the fact that PHP 3.0 had no concept of reference counting.
+  Zend adds full reference counting for every value in the system,
+  including resources.  As soon as a resource is no longer referenced
+  from any variable, it is automatically destroyed to save memory
+  and resources.  The most obvious example for the advantage in this
+  is a loop that has an SQL query inside it, something like
+  '$result = sql_query(...);'.  In PHP 3.0, every iteration resulted
+  in another SQL result-set allocated in the memory, and all of the
+  result sets weren't destroyed until the end of the script's execution.
+  In Zend, as soon as we overwrite an old result set with a new one,
+  the old result set which is no longer referenced, is destroyed.
+* Full support for nesting arrays and objects within each other, in
+  as many levels as you want.
+* Boolean type.  true and false are now constants of type boolean.
+  Comparing any other value to them would convert that value to a
+  boolean first, and conduct the comparison later.  That means, for
+  example, that 5==true would evaluate to true (in PHP 3.0, true
+  was nothing but a constant for the integer value of 1, so 5==true
+  was identical to 5==1, which was false).
+* Runtime binding of function names.  This complex name has a simple
+  explanation - you can now call functions before they're declared!
+* Added here-docs support.
+* Added foreach.  Two syntaxes supported:
+   foreach(array_expr as $val) statement
+   foreach(array_expr as $key => $val) statement
+* A true unset() implementation.  A variable or element that is unset(), is now
+  sent to oblivion in its entirely, no trace remains from it.
+* Output buffering support!  Use ob_start() to begin output buffering, ob_end_flush()
+  to end buffering and send out the buffered contents, ob_end_clean() to end buffering
+  without sending the buffered contents, and ob_get_contents() to retreive the current
+  contents of the output buffer.
+  Header information (header(), content type, cookies) are not buffered.  By turning
+  on output buffering, you can effectively send header information all throughout your
+  file, regardless of whether you've emitted body output or not.
+* Full variable reference within quoted strings:
+  ${expr}		- full indirect reference support for scalar variables
+  {variable}	- full variable support
+  For example:
+  $foo[5]["bar"] = "foobar";
+  print "{$foo[5]["bar"]}";  // would print "foobar"
+* Ability to call member functions of other classes from within member functions or from
+  the global scope. You can now, for example, override a parent function with a child function,
+  and call the parent function from it. 
+* Runtime information for classes (class name, parent, available functions, etc.).
+* Much more efficient syntax highlighter - runs much quicker, performs more reliably, and
+  generates much tighter HTML.
+* A full-featured debugger has been integrated with the language (supports breakpoints,
+  expression evaluation, step-in/over, function call backtrace, and more).
+
+
+Incompatabilities
+-----------------
+
+Zend claims 100% compatability with the engine of PHP 3.0, and is
+shamelessly lying about it.  Here's why:
+
+* static variable initializers only accept scalar values
+  (in PHP 3.0 they accepted any valid expression).  The impact
+  should be somewhere in between void and non existant, since
+  initializing a static variable with anything but a simple
+  static value makes no sense at all.
+
+* The scope of break and continue is local to that of an
+  include()'d file or an eval()'d string.  The impact should
+  be somewhat smaller of the one above.
+
+* return statement from a require()'d file no longer works.  It
+  hardly worked in PHP 3.0, so the impact should be fairly small.
+  If you want this functionality - use include() instead.
+
+* unset() is no longer a function, but a statement.  It was never
+  documented as a function so the impact should be no bigger than
+  nada.
+
+* The following letter combination is not supported within encapsulated
+  strings:  "{$".  If you have a string that includes this letter
+  combination, for example, print "{$somevar"; (which printed the
+  letter { and the contents of the variable $somevar in PHP 3.0),
+  it will result in a parse error under Zend.  In this case, you
+  would have to change the code to print "\{$somevar";
+  This incompatability is due to the full variable reference
+  within quoted strings feature added in Zend.

+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 = (pval *) emalloc(sizeof(pval));
+
+	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.
+
+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 "foo" 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).

+ 6. Setting variables in the symbol table
+ 7. Returning values from functions

+----------------- 
+
+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
