Installation
\nOpCache is compiled by default on PHP5.5+. However it is disabled by default. In order to start using OpCache in PHP5.5+ you will first have to enable it. To do this you would have to do the following.<\/p>\n

Add the following line to your php.ini:<\/p>\n

\n\n# zend_extension=\/full\/path\/to\/opcache.so (nix)\n# zend_extension=C:\\path\\to\\php_opcache.dll (win)\n\n<\/pre>\n
Note that when the path contains spaces you should wrap it in quotes:<\/p>\n
\n\n# zend_extension="C:\\Program Files\\PHP5.5\\ext\\php_opcache.dll"\n\n<\/pre>\n
Also note that you will have to use the zend_extension directive instead of the “normal” extension directive because it affects the actual Zend engine (i.e. the thing that runs PHP).<\/p>\n
Usage
\nCurrently there are four functions which you can use:<\/p>\n
opcache_get_configuration():<\/p>\n
Returns an array containing the currently used configuration OpCache uses. This includes all ini settings as well as version information and blacklisted files.<\/p>\n
var_dump(opcache_get_configuration());
\nopcache_get_status():<\/p>\n
This will return an array with information about the current status of the cache. This information will include things like: the state the cache is in (enabled, restarting, full etc), the memory usage, hits, misses and some more useful information. It will also contain the cached scripts.<\/p>\n
var_dump(opcache_get_status());
\nopcache_reset():<\/p>\n
Resets the entire cache. Meaning all possible cached scripts will be parsed again on the next visit.<\/p>\n
opcache_reset();
\nopcache_invalidate():<\/p>\n
Invalidates a specific cached script. Meaning the script will be parsed again on the next visit.<\/p>\n
opcache_invalidate(‘\/path\/to\/script\/to\/invalidate.php’, true);<\/p>\n","protected":false},"excerpt":{"rendered":"
