After reading another review on amazon before buying this book which said that it contained many errors I went ahead and purchased it anyway.
I was keen to prepare for the exam and thought this book was the right way to do it.
Using the book to get a general idea of what needed to be learned is quite handy, however the number of programming mistakes in this book as absolutely appaling. It would'nt be so bad if it was just spelling mastakes, I can live with that, but having functions with the parameters the wrong way round (on several occasions) among other things is not acceptable.
This book is supposed to prepare you for the Zend exam.If you use just this book alone to prepare for the exam you will fail.
If you do use it DOUBLE CHECK EVERYTHING with the php manual or you will surely suffer the consequenses.
The authors of this book should be ashamed with themselves as I, a non-professional at this point could probably do a better job.
You have been warned.
