Query: Dont buy this book if you have 2-3 months experience on PHP

This book is very basic learning of PHP...strictly only for PHP beginners. But even for beginners this book would surely get out of date. I thought this book would have some PHP object oriented concepts and code snippets, but it was not.So buy this book only if you have absolutely no knowledge of what is PHP and how to run the PHP code.
