(PECL apc >= 2.0.0)
apc_cache_info — Retrieves cached information from APC's data store
array apc_cache_info ([ string $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) 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.
Version | Description |
---|---|
3.0.11 | The limited parameter was introduced. |
3.0.16 | The "filehits" option for the cache_type parameter was introduced. |
Example #1 A apc_cache_info() example
<?php print_r(apc_cache_info()); ?>
The above example will output something similar to:
Array ( [num_slots] => 2000 [ttl] => 0 [num_hits] => 9 [num_misses] => 3 [start_time] => 1123958803 [cache_list] => Array ( [0] => Array ( [filename] => /path/to/apc_test.php [device] => 29954 [inode] => 1130511 [type] => file [num_hits] => 1 [mtime] => 1123960686 [creation_time] => 1123960696 [deletion_time] => 0 [access_time] => 1123962864 [ref_count] => 1 [mem_size] => 677 ) [1] => Array (...iterates for each cached file) )
