apcu_cache_info

(PECL apcu >= 4.0.0)

apcu_cache_info — Retrieves cached information from APCu's data store

Description

apcu_cache_info ([ bool $limited = FALSE ] ) : array

Retrieves cached information and meta-data from APC'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 APC cache data. This typically occurs when APC is not enabled.

Changelog

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