PHP Manual

apcu_cache_info

Retrieves cached information from APCu's data store

Description

arrayfalse apcu_cache_info(bool $limited = false)

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

Parameters

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.

Return Values

Array of cached data (and meta-data) or false on failure

Note: apcu_cache_info will raise a warning if it is unable to retrieve APCu cache data. This typically occurs when APCu is not enabled.

Changelog

Version Description
PECL apcu 3.0.11 The limited parameter was introduced.
PECL apcu 3.0.16 The "filehits" option for the cache_type parameter was introduced.
