Retrieves cached information and meta-data from APC's data store.

If limited is true, the return value will exclude the individual list of cache entries. This is useful when trying to optimize calls for statistics gathering.

If you get the following warning when using APCu functions via PHP's CLI SAPI:

  PHP Warning:  apcu_cache_info(): No APC info available.  Perhaps APC is not enabled? Check apc.enabled in your ini file

then check the status of `apc.enable_cli`. This is a separate INI entry for enabling APC via the CLI SAPI.
