Learning PHP

In a follow up to my previous post about reference materials, I’m on the lookout for a PHP reference that will teach me the basics of this server side language. It is undoubtedly one of the most popular languages today and as such I feel it is important to swot up a bit this summer.

It will be a topic that is covered when I go to University in Dundee this summer, but I’d be interested in using some PHP in a personal project this summer before I go. Nothing fancy, but just so I’m able to understand the principles. I already have this book which I’m slowly working through, and I’ve recently discovered this tutorial site which I will take a look at, but wondered if there were any other recommendations that people have?
