Turck MMCache for PHP

Protection of disk cache files by crc32 checksum
was implemented. mmcache_get/mmcache_put
cross-host security was fixed. Incorrect
optimization of "function test()
{$a=$GLOBALS['a']+1;}" was fixed. A crash when
including a nonexistent file with Zend Optimizer
was fixed. A "Clean" button was implemented in
"mmcache.php" to remove all expired data from
shared memory and disk cache. Additional
configuration directives "mmcache.keys",
"mmcache.sessions", and "mmcache.content" were
added to control where to cache data, session
data, and content.

Support for incomlete classes in mmcache_get()
was implemented. The PHP version is now checked.
A problem with include and include_once under
PHP 4.3.3 was fixed, along with the improper
"Cannot redeclare ()" error and an issue with
caching files under Windows when given absolute
paths but not drives. This release was tested
with PHP 4.3.3 and php5-200309021330.

HTTP caching of mmcache.php was disabled. Usage of
POSIX semaphores on Mac OS X was disabled.
Handling of scripts with PHP syntax errors was
fixed. ZE2 support was improved (tested with
php5-200308140730). This should be the last
version prior to the stable 2.4.0 release. Please
test this release as much as possible.

In this version, optimization of $GLOBALS[] for ZE2 was
implemented. The comparison with zero optimization
pattern was improved. The "mmcache.shm_only"
configuration directive was added to disable caching of
scripts on disk. It has no effect on session and content
caching. A bug with get_parent_class() and
is_subclass_of() was fixed.

This version now uses $_SERVER['PHP_SELF'] instead
of $PHP_SELF in encoder.php and
mmcache_password.php. Virtual host support was
improved. You can start mmcache with
"mmcache.enable=0" and enable it only for some
virtual hosts or directories. ZE2 compatibility was
improved (tested with PHP 5-200307290730). Some
serious bugs were fixed.
