wincache_scache_info()
(PECL wincache >= 1.1.0)
Retrieves information about files cached in the session cache
说明
wincache_scache_info([bool $summaryonly= FALSE
]): array
Retrieves information about session cache content and its usage.
参数
- $summaryonly
Controls whether the returned array will contain information about individual cache entries along with the session cache summary.
返回值
Array of meta data about session cache 或者在失败时返回FALSE
The array returned by this function contains the following elements:
- total_cache_uptime- total time in seconds that the session cache has been active
- total_item_count- total number of elements that are currently in the session cache
- is_local_cache- true is the cache metadata is for a local cache instance, false if the metadata is for the global cache
- total_hit_count- number of times the data has been served from the cache
- total_miss_count- number of times the data has not been found in the cache
scache_entries- an array that contains the information about all the cached items:
- key_name- name of the key which is used to store the data
- value_type- type of value stored by the key
- use_time- time in seconds since the file has been accessed in the opcode cache
- last_check- time in seconds since the file has been checked for modifications
- ttl_seconds- time remaining for the data to live in the cache, 0 meaning infinite
- age_seconds- time elapsed from the time data has been added in the cache
- hitcount- number of times data has been served from the cache
范例
Example #1 A wincache_scache_info() example
<pre> <?php print_r(wincache_scache_info()); ?> </pre>
以上例程会输出:
Array ( [total_cache_uptime] => 17357 [total_file_count] => 121 [total_hit_count] => 36562 [total_miss_count] => 201 [scache_entries] => Array ( [1] => Array ( [file_name] => c:\inetpub\wwwroot\checkcache.php [add_time] => 17356 [use_time] => 7 [last_check] => 10 [hit_count] => 454 [function_count] => 0 [class_count] => 1 ) [2] => Array (...iterates for each cached file) ) )
