apc_cache_info

Retrieves cached information from APC's data store

&reftitle.description; `array` `apc_cache_info` `string` `cache_type`"" `bool` `limited` false

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

&reftitle.parameters;

`cache_type`

- If `cache_type` is "`user`", information about the user cache will be returned.

  If `cache_type` is "`filehits`", information about which files have been served from the bytecode cache for the current request will be returned. This feature must be enabled at compile time using `--enable-filehits`.

  If an invalid or no `cache_type` is specified, information about the system cache (cached files) will be returned.

`limited`

- 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.

&reftitle.returnvalues;

Array of cached data (and meta-data)&return.falseforfailure;

`apc_cache_info` will raise a warning if it is unable to retrieve APC cache data. This typically occurs when APC is not enabled.

&reftitle.changelog;
