If you didn't get a chance to attend Matthew Turland's "New SPL Features in PHP 5.3" webcast, you can get caught up with the slides and source code he used:

Hope you were able to make it to the slides and excellent selection of upcoming webcasts leading up to CodeWorks 2009.

The webcasts are being recorded, but the recording of this session hasn't been posted yet. We'll update this post when it is.
