APC originated with Daniel Cogwell and George Schlossnagle, and was released by Community Connect, Inc. After the release of PHP5, Yahoo! modified APC to support the new Zend Engine, and it has since become part of PECL.
Alternative PHP Cache (APC) 是一个开放自由的 PHP opcode 缓存。它的目标是提供一个自由、 开放,和健全的框架,用于缓存、优化 PHP 中间代码。
此扩展被认为已无人维护及已消亡。然而,此扩展的源代码还可在 PECL GIT 找到: https://git.php.net/?p=pecl/caching/apc.git.
Note:
此扩展的代替者是: OPcache、 APCu、 Windows Cache for PHP 和 Session Upload Progress API。
