apcu_cache_info

(PECL apcu >= 4.0.0)

apcu_cache_info Retrieves cached information from APCu's data store

说明

array apcu_cache_info ([ bool $limited = FALSE ] )

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

参数

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.

返回值

Array of cached data (and meta-data) 或者在失败时返回 FALSE

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.

更新日志

版本 说明
3.0.11 The limited parameter was introduced.
3.0.16 The "filehits" option for the cache_type parameter was introduced.

范例

Example #1 A apcu_cache_info() example

<?php
print_r
(apcu_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/apcu_test.php
                    [device] => 29954
                    [inode] => 1130511
                    [type] => file
                    [num_hits] => 1

                    [access_time] => 1123962864
                    [ref_count] => 1
                    [mem_size] => 677
