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|false

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
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.
