I've purchased PHP and Mysql for dynamic web sites, and a PHP book by Larry Ullman, well both were by LarryUllman. I found'em on Amazon.com. They are over PHP 3 and 4, but I think you can't go wrong with any newer book that covers what you need. I'm far from a programmer, VERY FAR, but it helped me learn a few details for small projects I needed. I wish I had more time to pursue it, as PHP is such a powerful scripting language.
