apc_cache_info — Retrieves cached information from APC's data store
$cache_type = ""
[, bool $limited = false
]] )Retrieves cached information and meta-data from APC's data store.
cache_type
If cache_type is "user",
information about the user cache will be returned.
If cache_type is "filehits",
information about which files have been served from the bytecode cache
for the current request will be returned. This feature must be enabled at
compile time using --enable-filehits
.
If an invalid or no cache_type is specified, 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 useful when trying to optimize calls for statistics gathering.
Array of cached data (and meta-data) 或者在失败时返回 FALSE
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.
