Query: The Best for beginer-intermediate

This is not the book to be used for developing an e-commerce site (security issues left out)nor is it for advanced PHP features nor is it reference of all the PHP features. Its a book for someone who has had some little exposure to some other programming language and would like to develop a web site in PHP. This book takes from you from beginning through intermediate level and it does it very well and very clearly without confusing you with endless options and parameters and permutations of every PHP function. It covers the most usefull and basic fucntions and does a very good job. I have three books on PHP, this is the one I start with to learn a concept because it is quick, clear, and to the point. As I want to learn more advanced features I consult other books later or php.net
