On a related note, I’m also doing a Sitepoint “Talk with the Experts” session on 11th April (early morning UK time, as a special treat for everyone in Europe and further east, that doesn’t happen often!). There are more details here: http://www.sitepoint.com/forums/showthread.php?1012242-Talk-Object-oriented-PHP-with-the-Experts and I hope you can join me then.
I’m delighted to announce that my new video course on Object-Oriented PHP is now available on Learnable! It’s very much an introduction, aiming to cover WHY objects are so cool as well as how to declare and use one. The course is a mix of video (filmed in my kitchen, welcome to my home everyone!), screencast, a couple of exercises for you to try, and also plenty of sample code to download. If you are just looking to get started with OOP, or know someone who is, then hopefully this will help you out.
