(PECL apcu >= 4.0.0)

apcu_cache_info Retrieves cached information from APCu's data store


apcu_cache_info(bool $limited = false): array|false

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



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.


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.

If you get the following warning when using APCu functions via PHP's CLI SAPI:

PHP Warning: apcu_cache_info(): No APC info available. Perhaps APC is not enabled? Check apc.enabled in your ini file

then check the status of `apc.enable_cli`. This is a separate INI entry for enabling APC via the CLI SAPI.
