I passed the PHP5 certification a couple of weeks ago after Engine (www.enginecreative.co.uk) kindly sponsored me. It was more of a refresher for me, though the XML chapters have been extremely useful since. I previously hadn’t really touched PHP’s DomDocument object or SimpleXML.
It’s definately worth doing, the exam itself isn’t that hard. It’s more of a memory test. The study will however give you a concrete foundation to build upon. By this I mean, if you ever suffer the “is this the best way” syndrome (like I do) you’ll always have something to fall back on.
As a heads up for the exam, you’ll find a lot of the questions are trick questions. Don’t take any of them at face value. There are often slight syntax errors in the examples which can be tricky to spot!
