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.

Example #1 A apc_cache_info() example
<?php
print_r ( apc_cache_info ());
?>
以上例程的输出类似于:
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) )
