The process of installing OPcache varies depending on which version of PHP you're running. Please refer to the appropriate section below.
Nota:
If you want to use OPcache with » Xdebug, you must load OPcache before Xdebug.
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.

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.
