apcu_cache_info

(PECL apcu >= 4.0.0)

Retrieves cached information from APCu's data store

array apcu_cache_info ([ bool $limited = false ] )

Retrieves cached information and meta-data from APC's data store.

Parameters:

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.

Returns:

Array of cached data (and meta-data) or FALSE on failure

Note: apcu_cache_info() will raise a warning if it is unable to retrieve APC cache data. This typically occurs when APC is not enabled.

Changelog:

3.0.11

The limited parameter was introduced.

3.0.16

The "filehits" option for the cache_type parameter was introduced.

Examples:

A apcu_cache_info() example

<?php
print_r(apcu_cache_info());
?>

The above example will output something similar to:

Array
(
    [num_slots] => 2000
    [ttl] => 0
    [num_hits] => 9
    [num_misses] => 3
