Changes are bug-fixes mostly, but also synchronizes bundled GD
with GD 2.0.22 and updates PCRE to version 4.5. Several NetBSD
patches were integrated too, so future pkgsrc updates would
be even more smooth.

Some highlights of changes since 4.2.3:
* PCRE updated to 4.3, GD to 2.0.15
* improved Apache2 support
* much improved stream & URL wrapper support, output compression support
* added CLI (Command Line Interface) SAPI
* debug_backtrace() backported from ZendEngine2
* faster build system
* huge number of other bug fixes and improvements
Packaging changes:
* 'pcre', 'xml', and 'session' modules folded back into main package -
'pcre' and 'xml' is required by PEAR, and 'session' is just too essential
to be separate
* 'gd' module now uses bundled PHP GD library, which is better integrated
* PHP modules use shared distinfo when possible to ease future PHP updates
* ${PREFIX}/bin/php is now CLI version, ${PREFIX}/libexec/cgi-big/php
remains CGI version
- Fixed start up failure when mm save handler is used and there is multiple
SAPIs are working at the same time. (Yasuo)
- Fixed a buffer overflow in the RFC-1867 file upload code (Stefan)
<===> SECURITY NOTE <===>
Note that the buffer overflow fix is a major security fix. Quoting from
the security advisory at:
http://security.e-matters.de/advisories/012002.html
"PHP supports multipart/form-data POST requests (as described in RFC1867)
known as POST fileuploads. Unfourtunately there are several flaws in the
php_mime_split function that could be used by an attacker to execute
arbitrary code. During our research we found out that not only PHP4 but
also older versions from the PHP3 tree are vulnerable.
[...]
"If you are running PHP 4.0.3 or above one way to workaround these bugs is
to disable the fileupload support within your php.ini (file_uploads = Off).
If you are running php as module keep in mind to restart the webserver.
Anyway you should better install the fixed or a properly patched version to
be safe."
- Introduced a new $_REQUEST array, which includes any GET, POST or COOKIE
variables. Like the other new variables, this variable is also available
regardless of the context.
- Introduced $_GET, $_POST, $_COOKIE, $_SERVER and $_ENV variables, which
deprecate the old $HTTP_*_VARS arrays. In addition to be much shorter to
type - these variables are also available regardless of the scope, and
there's no need to import them using the 'global' statement.
Other relevant changes include:
- Bug fixes to prevent crashes on unexpected input.
- Huge performance improvements, especially in thread-safe code.
- Introduced extension version numbers.
- Added support for single dimensional SafeArrays and Enumerations.
Added an is_enum() function to check if a component implements an
enumeration.
- Improved speed of the serializer/deserializer.
- Floating point numbers are better detected when converting from strings.
- Added import_request_variables(), to allow users to safely import form
variables to the global scope
- Add config option (always_populate_raw_post_data) which when enabled
will always populate $HTTP_RAW_POST_DATA regardless of the post mime
type
- Added getmygid() and safe_mode_gid ini directive to allow safe mode to do
a gid check instead of a uid check.
- Assigning to a string offset beyond the end of the string now automatically
increases the string length by padding it with spaces, and performs the
assignment.
