apc_cache_info

(PECL apc:2.0-3.0.9)

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

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.

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.
