I'm really not sure what happend with this book, and I won't make any assumptions other than it was not ready when it went to press.

So many functions are poorly described, have the wrong parameters, or are just missing that I felt this book was a waste of money. PHP has so much better information on their website, including an annotated manual, I've generally found opening up the Pocket Reference a waste of my time. It is so much easier (and more accurate) just to go to the online documentation.

It just amazes me that a colaboration between O'Reilly and Rasmus Lerdorf didn't work out better.
