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());
?>
以上例程会输出：
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)
)
)

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.
