apc_cache_info — Retrieves cached information from APC's data store
Description
Retrieves cached information and meta-data from APC's data store.
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.
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 usefull when trying to optimize calls for statistics gathering.
ChangeLog
| Version | Description |
|---|---|
| 3.0.11 | The limited parameter was introduced. |
| 3.0.16 | The "filehits" option for the cache_type parameter was introduced. |
