### Beschreibung

array wincache_scache_info ([ bool `$summaryonly` = false ] )

Retrieves information about session cache content and its usage.

### Parameter-Liste

`summaryonly`

  Controls whether the returned array will contain information about individual cache entries along with the session cache summary.

### Rückgabewerte

Array of meta data about session cache Im Fehlerfall wird `FALSE` zurückgegeben.

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

### Beispiele

Beispiel #1 A wincache_scache_info() example

`<pre>
<?php
print_r(wincache_scache_info());
?>
</pre>`

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

    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)
            )
    )
