Coming from "The PHP Company", I fully expected this book to be "up-to-snuff" on everything it covered. I was sadly mistaken.I barely made it past the third page of the first chapter, and I had to shelf it. The technical errors, the grammatical errors (I know, I'm not perfect), and the cheesey analogies all made it a very uncomfortable experience.As another reviewer mentioned, this book needs to be updated to reflect the errata and such. I'm very displeased with it, and I will be sharing my opinion with Zend.
