Publisher review:eAccelerator is a free open-source PHP accelerator, optimizer, encoder and dynamic content cache. eAccelerator is a free open-source PHP accelerator, optimizer, encoder and dynamic content cache.
It increases the performance of PHP scripts by caching them in their compiled state, so that the overhead of compiling is almost completely eliminated. It also optimizes scripts to speed up their execution.
eAccelerator typically reduces server load and increases the speed of your PHP code by 1-10 times.
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 stores compiled PHP scripts in shared memory and executes code directly from it. It creates locks only for a short time, while searching for a compiled PHP script in the cache, so one script can be executed simultaneously by several engines. Files that can't fit in shared memory are cached on disk only.
eAccelerator also contains a PHP encoder and loader. You can encode PHP scripts using encoder.php in order to distribute them without sources.
Encoded files can be run on any site which runs PHP with eAccelerator. The sources of encoded scripts can't be restored because they are stored in a compiled form and the encoded version doesn't contain the source.
Of course, some internals of the scripts can be restored with different reverse engineering tools (disassemblers, debuggers, etc.), but it is not trivial.
eAccelerator 0.9.5.3 is a PHP script for Security Systems scripts design by eAccelerator.
It runs on following operating system: Windows / Linux / Mac OS / BSD / Solaris.
