|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

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.

  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.
- Fix -L path in libphp4.module to make ApacheSSL compile without errors
- Fix StripSlashes so it correctly decodes a \0 to a NUL

July 04 1998 Version 3.0.1
- echo/print of empty strings don't trigger sending the header anymore.
- Implemented shift left and shift right operators (<< and >>)
- Compile fix for cc on HP-UX.
- Look for beta-version Solid libraries as well.
- Make GD module show more info in phpinfo().

- Fix for Oracle extension on OSF/1.
- Fix gd 1.3 bug in ImageColorAt().
- pg_loread() hopefully handles binary data now.
- Turned off some warnings in dns.c
- Added ImageTTFBBox() and made ImageTTFText() return bounding box.
- Added constants for Ora_Bind()'s modes.
- Renamed all hash_*() routines to _php3_hash_*() to avoid clashes with other
  libraries.
- Changed uodbc default LONG behaviour: longreadlen 4096 bytes, binmode 1.
  The module now actually uses the php.ini settings.
- New PostgreSQL functions:  pg_fetch_row(), pg_fetch_array()
  and pg_fetch_object()
- Fix a segmentation fault when calling invalid functions in certain
  circumstances
- Fix bug that caused link-related functions to not pay attention to
  run-time safe mode setting (it was using whatever was set at compile time).

June 6 1998 Version 3.0
- Add checkdnsrr function (check availability DNS records)
- Add getmxrr function (get MX hostnames and weights)
- Fixed bug in nl2br() function
- Fix for an RC5 related problem in the Sybase module, when dealing
  with very long data types.
- Speed up string concatenation by roughly a factor of 2
- Add escape-handling to date function
- Make base64 functions binary safe
- Add strrpos function to complement strpos function added in RC5
- Add ltrim function (strips only at the start of string)
- Add rtrim as an alias to chop() for completeness sake
- Add trim function (similar to chop, except it strips at the start as well)
- Added 2 optional args to fsockopen function - errno and errstr
- Fixed bug in split() function related to leading matches
- Fixed problem in error_log() function (thanks to Jan Legenhausen)
- empty("0") was returning true - fixed
- Removed the old sybsql module.  Use the new sybase_*() functions instead.
- 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
  operations, but this can be overiden by fopen.  Do not open files in text
  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
- Fix for feof() when used on a socket
- Fix off-by-one error in fgets() when used on a socket
- Fix bug in ImageSetPixel() (Thanks to ecain@Phosphor.net)

March 31 1998 Version 3.0 Release Candidate 3
- Tiny bugfix for magic_quotes_sybase
- Fix Apache build problems introduced in RC2
- $a["0"]==$a[0] fix
- Apache-1.3 build changes to support 100% automatic builds and shared library
  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()
- Fixed Ora_GetColumn() bug when fetching strings
- 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
- Add "-c" command line flag for specifying path to php3.ini file
- 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
- Fixed to compile and run on SunOS 4.1

  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
- Fixed a nasty corruption bug in eval() and show_source() that resulted in
  script termination (e.g. eval("exit();").
- Fixed a syntax highlighting problem with keywords used as variable
  names.
- Fixed a possible crash and/or file descriptor leak
- Fixed line number being off by one in #! shell style execution

- Fixed an unlikely crash bug in the parser, with uninitialized array elements
  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 Stig and Tin's bdf2gdfont script to extra/gd directory
- Added join() as an alias to implode()
- Made implode() accept arguments in the order used by explode() as well
- Made $php_errormsg local in function calls
- Fixed Apache configuration directive bugs
- Added a number of .ini directives to Apache .conf directive list
- Fixed a 'memory leak' with strtok()
- echo/print now handle binary data correctly.
- NEW now accepts any expression for the class name argument.
- Add ImageDashedLine() GD function
- Add arg_separator .ini directive so the '&' GET method separator can be
  changed to ';' for example.  Corresponding php3_arg_separator Apache .conf
  directive works as well.
- Walked around an implementation side effect of switch().  <? switch(expr) { ?>
  now works.
- Added memory caching, resulting in a significant performance boost
- Added support for for(): .. endfor; loops
- Added a new predicate - empty($var).  Returns true if $var is not set,
  or is FALSE.  Returns false otherwise.

- Added 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).

  display.
- Added highlight_string() - behaves like highlight_file(), only instead
  of highlighting a file, it syntax highlights the contents of its
  argument.

  supported for downwards compatability.
- Fixed a bug in class inheritence - member functions with upper case
  letters in their names couldn't be redefined.

  better describe what it does, and pay attention to the setting.
- Added optional parameter to the file(), readfile()  and fopen() functions
  to look for files located in the include path.
- Fixed bug that allowed the file() and readfile() to open files in the
  include path inadvertantly.
- Fixed a (documented) bug in printf()/sprintf() with hard limited strings
  and alignment (e.g. %-.20s).

  that record had been marked for deletion.
- Fixed bug in dbase library that stomped on the deleted flag of the first

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.

  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

  (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

  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.
