Padraic Brady has posted the third chapter of his "Zend Framework: Surviving The Deep End" book. It focuses on the Models in the Model-View-Controller (MVC) applications.

Today Chapter 3, The Model, has entered the online book. Apart from some early jitters when PHPIDS (an intrusion detection system I use) lost the plot and commenced a vendetta against Opera, the new chapter is fully operational.

If you get these first chapters, you'll notice that there's some color coding going on with status labels. Padraic is using this to give you some feedback as to the level of completion a certain chapter is in. He notes:

I've decided to start noting in these announcements that these early Chapters are akin to drafts. While they are written as complete units, it's intended to revisit them every few weeks for improvement until a final version emerges to be forever immortalised as a first edition of the book.
