(PECL apc >= 2.0.0)

apc_cache_info Retrieves cached information from APC's data store

Descrizione

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

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

Elenco dei parametri

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.

Valori restituiti

Array of cached data (and meta-data) o FALSE in caso di fallimento

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