# apc_cache_info

(PECL apc >= 2.0.0)

apc_cache_info — Retrieves cached information from APC's data store

### Beschreibung

array apc_cache_info ([ string `$cache_type` [, bool `$limited` = false ]] )

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

### Rückgabewerte

Array of cached data (and meta-data)Im Fehlerfall wird `FALSE` zurückgegeben.

> Hinweis: apc_cache_info() will raise a warning if it is unable to retrieve APC cache data. This typically occurs when APC is not enabled.

### Parameter-Liste

`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.

### Changelog

Version | Beschreibung
--- | ---
3.0.11 | The `limited` parameter was introduced.
3.0.16 | The "filehits" option for the `cache_type` parameter was introduced.
