PHP startup kit

Recently I've got involved in deploying Open Source Web 2.0 applications (specifically, phpBB, Wordpress and MediaWiki), so I had to bite the PHP/MySQL bullet. If you're in the same situation, I would strongly recommend these books:

• Programming PHP
• Professional PHP5 (Programmer to Programmer)
• The PHP Anthology: 101 Essential Tips, Tricks & Hacks (Anthology)

Full disclosure: If you click on one of the above links and actually buy the book, I might get around $1.00 from Amazon
