This is a fantastic function that will allow you to cache your data. By default it will cache using memcache, however if you do not have memcache installed or a connection cannot be achieved it will fall back to file based cache.
The single function supports cache read, cache write, cache clear key and cache clear all. The cached data can be given an expirey time so that your data does not become stale.
Usage is very simple and the performance results of caching using memcache are fantastic.
