To use this application component, the APC PHP extension must be loaded.
Alternatively APCu PHP extension could be used via setting useApcu to true.
In order to enable APC or APCu for CLI you should add "apc.enable_cli = 1" to your php.ini.
See Cache for common cache operations that ApcCache supports.
For more details and usage information on Cache, see the guide article on caching.
