I found your blog from the web designers forum – i see you post quite a lot there

I just have one comment to make re your article. While sessions are a very quick way to achieve what you want you should really be using a proper caching framework such as APC – or alternative php cache. It’s quite easy to you simply set and retreve values from the cache using built in functions like apc_add and apc_fetch. More importantly you can also clear whole or part of the cache using apc_delete – you could run this in your destroy method in your classes for eg.
