Looking for a comprehensive PHP tutorial

Hi, I am looking for a comprehensive handholder tutorial, that introduces the various aspects of PHP, step by step and let's u see the big picture. I have come across tons of PHP learnware which is like "how to do this" and "how to do that". But that still doesn't introduce the language to the beginner in an orderly manner. Any suggestions, links, will be greatly appreciated. Or, if someone (experienced in PHP) thinks we must come up with such a comprehensive tutorial, we can perhaps team up ;) Ash
