wincache_ucache_info — Retrieves information about data stored in the user cache
wincache_ucache_info ([ bool $summaryonly = false [, string $key = NULL ]] ) : array|false
Retrieves information about data stored in the user cache.
summaryonly
Controls whether the returned array will contain information about individual cache entries along with the user cache summary.
key
The key of an entry in the user cache. If specified then the returned array will contain information only about that cache entry. If not specified and summaryonly
is set to false
then the returned array will contain information about all entries in the cache.
Array of meta data about user cache or false
on failure
The array returned by this function contains the following elements:
total_cache_uptime
- total time in seconds that the user cache has been active total_item_count
- total number of elements that are currently in the user 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 ucache_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 is_session
- indicates if the data is a session variable 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 Example #1 Using wincache_ucache_info()
<?php wincache_ucache_get('green'); wincache_ucache_set('green', 2922); wincache_ucache_get('green'); wincache_ucache_get('green'); wincache_ucache_get('green'); print_r(wincache_ucache_info()); ?>
The above example will output:
Array ( ["total_cache_uptime"] => int(0) ["is_local_cache"] => bool(false) ["total_item_count"] => int(1) ["total_hit_count"] => int(3) ["total_miss_count"] => int(1) ["ucache_entries"] => Array(1) ( [1] => Array(6) ( ["key_name"] => string(5) "green" ["value_type"] => string(4) "long" ["is_session"] => int(0) ["ttl_seconds"] => int(0) ["age_seconds"] => int(0) ["hitcount"] => int(3) ) ) )
