Here you will find corrections, tips, clarifications, and samples related to the PHP reference book. You are encouraged, if you find an error or something that needs clarification, to post a comment to the blog so it can be addressed in a post and fixed for later versions (that’s what I call wishful thinking).
If you don’t already have a copy of the PHP book, I encourage you to get a print copy from any of the online retailers. Remember, a free PDF version will always be available and the entire book is issued under Creative Commons: Attribution-NonCommercial-ShareAlike 2.0.
This PHP reference includes numerous additional tips, the basics of PHP, MySQL query examples, regular expressions syntax, and two indexes to help you find information faster: a common language index and a function index.
