I have recently started to teach the PHP Social Web Applications course in HIT. I am currently updating my training material about facebook applications development in PHP.
I have just completed to develop Abelski Geeks, a simple basic facebook application that will assist other developers in doing their first steps.
The following video clip explains how to set up a simple facebook application on the facebook platform. It uses Abelski Geeks source code.
You can find the source code together with additional slides that explains how to install it on your end in my on going PHP Facebook Applications course, which you can find available for free personal and academic usage at www.abelski.com.
