(PECL apc:2.0-3.0.9)

apc_cache_info — Retrieves cached information (and meta-data) from APC's data store

### Description

array apc_cache_info ([ string `$cache_type` [, bool `$limited` ]] )

### Return Values

Array of cached data (and meta-data), or `FALSE` on failure

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

### Parameters

`cache_type`

  If `cache_type` is "user", information about the user cache will be returned; otherwise, 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 usefull when trying to optimize calls for statistics gathering.

### ChangeLog
