best book(s) for learning PHP and PHP w/ MYSQL

Hi guys. I have dabbled in PHP for a while. Mainly PHP parsing XML and outputting HTML. I have been learning on an "as needed" basis by reading documentation on php.net, but I would like to get a really good overview of PHP and MYSQL. I also have a large project looming. This project would be creating a reservation system and calendar. Do any of you have a suggestion on the books you have found especially useful, particularly, on PHP with MYSQL databases.
