One, Apc_store ($key, $value, $time) and Apc_add ($key, $value, $time) methods are similar, parameters such as session, $key is a key value, $value is a value, (like an array), $time the cache time , the default is permanent.
Second, Apc_fetch ($key) gets the cache with the key value of $key
Third, Apc_delete ($key) Clear Cache
I encapsulated it as a class, as an example
