The book is getting closer. Yesterday we had an official announcement on the php|architect website, which pointed to the order page. It looks like Marco is giving a 10% preorder discount, so everyone should order 10 copies today, and effectively get a free copy.
I would have also emphasized unit testing in the blurb. While there are a few PHP books out there which have chapters or sections on unit testing, I don’t believe there is any other book which emphasizes the practice as much as I have. Unit tests are not only present in the code download for each chapter, but are integral to the explanations in each chapter as well. Many times when I present examples of working code, it is within the context of a unit test. I also tried to explain the basics of Test Driven Development, and have a few examples shown using TDD iterations.
The Adapter chapter is off to layout so we are down to the last few chapters! I am really looking forward to holding the dead tree edition
