Books

PHP in a nutshell
Good, compact reference to the language, but not a place to start if you are learning. Useful function references.

Learning PHP 5
Introduction to PHP with a useful chapter-by-chapter basis. I found some stuff quite difficult to understand, and the database section assumes you are using PEAR rather than MySQL.

PHP Cookbook
Very useful worked examples. Desgined around answering questions where each chapter covers a differant subject in PHP. A useful book once you've got going, but not the place to start with PHP.
Visual Quickstart Guide - MYSQL
Good, easy to understand reference to MySQL and includes a section on PHP. Good reference to MySQL, but some sometimes difficult to understand examples.
