One thing to note is that 'is_local_cache' field returned as one of the metadata in the array for User Cache will always return boolean false as User Cache is always global and never local.
(PECL wincache >= 1.1.0)
wincache_ucache_info — Retrieves information about data stored in the user cache
Retrieves information about data stored in the user cache.
summaryonlyControls 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 ou false em caso de falha
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
Exemplo #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());
?>O exemplo acima produzirá:
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)
)
