I have written an extensive web application frameworks, and I keep seeing my execution time and memory-usage growing. Right now it is not a problem, but before it get's out of hands I will need to create a good cache engine. My cache engine requires that I can cache method results, based on multiple parameters. What would be a good way to implement this? I know this propably a well-formed question, but before I start, I want to be sure I'll do it the right way. Has anyone got any experience with this, or can anyone give me some pointers on where to start looking?

I have seen some people using stornig cached items in shared memory. This is explained in some detail here: http://www.danga.com/memcached/ There are PHP client APIs available. Alternatively PEAR offers some interesting caching solutions although i have not investigated them thoroughly ( http://pear.php.net/ ) Caching brings all sorts of wierdness out in applications due to multiple states of data being present in different layers in a system, so be careful.
