Installation

The process of installing OPcache varies depending on which version of PHP you're running. Please refer to the appropriate section below.

Hinweis:

If you want to use OPcache with » Xdebug, you must load OPcache before Xdebug.

PHP 5.5.0 and later

OPcache can only be compiled as a shared extension. If you have disabled the building of default extensions with --disable-all , you must compile PHP with the --enable-opcache option for OPcache to be available.

Once compiled, you can use the zend_extension configuration directive to load the OPcache extension into PHP. This can be done with zend_extension=/full/path/to/opcache.so on non-Windows platforms, and zend_extension=C:\path\to\php_opcache.dll on Windows.

PHP 5.2, 5.3 and 5.4

Diese » PECL-Extension ist nicht Teil von PHP.

Information zur Installation dieser PECL-Extension finden sie im Kapitel Installation von PECL-Extensions. Zusätzliche Informationen wie neue Releases, Downloads, Quelldateien, Maintainerinformation und ein CHANGELOG finden Sie hier: » http://pecl.php.net/package/ZendOpcache.

Eine DLL-Datei für diese PECL-Erweiterung steht derzeit nicht zur Verfügung. Weitere Details finden Sie im Abschnitt zum Kompilieren für Windows.

Recommended php.ini settings

The following settings are generally recommended as providing good performance:

opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000
opcache.revalidate_freq=60
opcache.fast_shutdown=1
opcache.enable_cli=1

You may also want to consider disabling opcache.save_comments and enabling opcache.enable_file_override, however note that you will have to test your code before using these in production as they are known to break some frameworks and applications, particularly in cases where documentation comment annotations are used.

A full list of configuration directives supported by OPcache is also available.

While the "suggested" opcache settings for php.ini might be appropriate for a production server, you're going to want to change several while you're developing, or you're not going to see any changes to your code. Get familiar with what they mean before blindly pasting that into php.ini and assuming things are going to work well.
