Codebase updates
Ben has recently published some code for routing requests to the correct controllers and views in a PHP MVC framework, so I've spent some of my weekend integrating it into my codebase (yep, this is the sort of thing I do on weekends).
Mapping URLs to site functionality has always seemed quite clumsy in my projects to date; Ben's solution has quite a Rails feel to it and is definitely the most elegant method I have encountered to date.
