'''Zend OpcacheOPcache'''<ref>{{cite web

Line 67 ⟶ 68:

| accessdate = 2013-02-13}}</ref> component of [[Zend Server]] and Zend Server Community Edition bundled with the PHP language itself.<ref name="zend-opcache" /> Zend OpcacheOPcache 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 OpcacheOPcache 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 OpcacheOPcache mid of March 2013.

Starting with PHP 5.5 the Zend OpcacheOPcache is integrated and shipped with PHP.<ref name="zend-opcache">{{cite web
