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) 
       ) 
    )
