This is a list of PHP accelerators.

Alternative PHP Cache (APC)

Alternative PHP Cache is a free and open (PHP license) framework that caches the output of the PHP bytecode compiler in shared memory, thus reducing parsing and disk I/O overhead for later requests; and a shared memory cache for user data. For an application consisting of a large source code base such as Drupal, a 3x increase in page generation speed is possible as a result.[1]

It has been used at Facebook and has a mature codebase thanks to numerous contributors, including Facebook itself.[2]

APC was originally scheduled for inclusion into the PHP core no later than PHP 6.[3] While multiple accelerator projects were considered desirable,[4] the focus has since moved to Optimizer Plus,[5][6] and, later, Zend Opcache that is included in the core distribution as of PHP 5.5.[7] Since March 2013, a beta version of APCu (APC User Cache) is available, in which all opcode caching abilities have been removed to support user caches in shared memory using the familiar APC API.[7]

eAccelerator

{{Multiple issues|{{MOS|section|date=February 2013}}{{Update|section|inaccurate=y|date=February 2013}}
}}

eAccelerator was born in December 2004 as a fork of the Turck MMCache project. Turck MMCache was created by Dmitry Stogov and much of the eAccelerator code is still based on his work. eAccelerator also contained a PHP encoder and loader, but the development staff discontinued the encoder and removed this feature after December 2006.

  • Website: http://eaccelerator.net/
  • PHP version: Supports PHP 4 and all PHP 5 thread-safe releases including 5.4. In older releases, the encoder will only work with PHP versions from the 4.x.x branch. eAccelerator will not work with any other versions of PHP. eAccelerator can only be used with the thread-safe version of PHP.
  • Latest stable version: 0.9.6.1 (2010-05-31)
  • Status: Dormant, potentially dead (no new releases since July 2012). The last public activity was the transfer to Github by Hans Rakers. The master branch supports PHP 5.4.

ionCube PHP Accelerator

Launched in 2001, ionCube PHP Accelerator (PHPA) was the first freely available PHP accelerator to compete with the commercial Zend Cache product. Created before ionCube Ltd. was founded and at a time when the performance of PHP was regarded as lackluster when compared to other popular web programming languages,{{Citation needed|date=December 2010}} PHPA showed that PHP can compete with other languages performance-wise.{{Citation needed|date=December 2010}} Although the author of PHPA chose to keep the project closed source in response to early concerns raised by Zeev Suraski of Zend Technologies about the effect that an open source rival might have on their commercial alternative, the availability of PHPA on a wide variety of platforms led to its extensive adoption worldwide from small sites to Yahoo!.{{Citation needed|date=December 2010}} It also inspired the redevelopment of APC to use the shared memory execution techniques that PHPA and Zend Cache had adopted instead of deserialization on each request that incurred performance penalties.{{Citation needed|date=December 2010}}

As for now it is available as try & buy software supporting PHP up to version 7.1.

Turck MMCache

Turck MMCache is now discontinued.{{citation needed|date=December 2010}} eAccelerator is a fork of Turck MMCache.

XCache

XCache is a fast, stable PHP opcode cacher that has been tested and is now running on production servers under high load. It is tested on GNU/Linux and FreeBSD and supported under Windows, for thread-safe and non-thread-safe versions of PHP. This relatively new opcode caching software has been developed by mOo, one of the developers of Lighttpd, to overcome some of the limitations of the existing solutions at that time; such as being able to use it with new PHP versions as they arrive.

  • Website: http://xcache.lighttpd.net/
  • PHP version: full support for up to PHP 5.6
  • Latest stable version: 3.2.0 (Released on 2014-9-18)
  • Status: Dormant, potentially dead (No release since 2014)
  • Download link: http://xcache.lighttpd.net/wiki/ReleaseArchive
  • Official installation help: http://xcache.lighttpd.net/wiki/InstallFromSource

Nusphere PhpExpress

PhpExpress is a free PHP opcode cache that loads both Nu-Coder (commercial) encoded and plain PHP files directly into the PHP engine, saving loading time and boosting performance of PHP applications. It's available on Windows, Linux, FreeBSD, NetBSD, Mac OS X, and Solaris.

  • Download link: http://www.nusphere.ru/files/download/NuSphere-PhpExpress-3.0.zip
  • Official installation help: http://www.nusphere.com/kb/phpexpressmanual/part1.htm#2
  • Website: http://www.nusphere.com/products/phpexpress.htm
  • PHP version: PHP 4.3 to 5.3
  • Latest stable version: 3.1
  • Status: Potentially dead (no new releases since Jan 2012 and they are not responding to enquires). The last supported version of PHP was 5.3.

Zend Opcache (ex. Zend Optimizer+)

Zend Opcache[8] is an open source[9] component of Zend Server and Zend Server Community Edition. Zend Opcache speeds up PHP execution by opcode caching and optimization. It stores precompiled script bytecode in shared memory. As of version 7.0 it can store precompiled script bytecode on disk. This eliminates the stages of reading code from the disk and compiling it on future access. For further performance improvements, the stored bytecode is optimized for faster execution. Unlike Zend Optimizer, Zend Opcache doesn't load files encoded by Zend Guard. Zend provides another component, Zend Guard Loader, in order to load encoded applications with Zend Server and Zend Server Community Edition.

Zend Optimizer+ was [https://github.com/php/php-src/commit/8d35170c5fe9b9c0c864b7a6c4dc6b0149809569 renamed] to Zend Opcache mid of March 2013.

Starting with PHP 5.5 the Zend Opcache is integrated and shipped with PHP.[10]

  • Website: http://pecl.php.net/package/ZendOpcache
  • Sources: https://github.com/zend-dev/ZendOptimizerPlus/
  • PHP version: full support for PHP 5.2+
  • Latest stable version: 7.1.6
  • Status: Actively maintained

Zend Platform

Zend Platform (formerly Zend Cache and then Zend Accelerator) is a commercial Web Application Server product. It has a complete set of performance capabilities that includes more than a simple PHP accelerator. Features include code caching/acceleration, data caching, content (html output) caching, download optimization and off-line (asynchronous) processing capabilities that can result in significant performance improvements for most PHP applications. It also includes detailed PHP monitoring and root cause analysis support to help in tuning and debugging, session fail-over support for HA (High Availability) needs and other integration capabilities including Java integration.

Zend Platform and Zend Core are now in 'end of life' status and are replaced with Zend Server.[11]

Windows Cache Extension for PHP

A free, open source (New BSD License), PHP accelerator developed by Microsoft for PHP under Windows. The extension includes PHP opcode cache, file cache, resolve file path cache, object/session cache, file change notifications and lock/unlock API's. Combination of all these caches results in significant performance improvements for PHP applications hosted on Windows. The extension is primarily used with Internet Information Services and non-thread-safe build of PHP via FastCGI protocol.

  • Website: http://www.iis.net/expand/WinCacheForPHP
  • PHP version: works with PHP 5.2 (VC6 NTS), 5.3 (VC9 NTS), 5.4 (VC9 NTS), 5.5 (VC11 NTS), 5.6 and 7.0, source code available
  • Latest stable version: 2.0.0.8 (2016-11-09)
