apc_cache_info

(PECL)

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

说明

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

返回值

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

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

参数

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.

更新日志

版本说明
3.0.11 The limited parameter was introduced.
