To avoid this, do instead: This function will attempt to fetch an item from the cache store. We can easily abstract that into the following base class. I think we can achieve this if we store TTL out of the data in some way I could track it with the getmypid function, which returned a different value upon every request, but only from a limited set.

Caching in PHP using the filesystem, APC and Memcached

It seems the 0 default setting will not work on some ap. This function will save an item to the cache store. Memory-based caching might be the solution.
