There are some useful tutorials and script tutorials on http://www.sitepoint.com as well. There is also http://phpbuilder.com/ but I'm unsure on how useful it may be.
Something I probably would have liked when learning PHP: http://devzone.zend.com/article/627-PHP-101-PHP-For-the-Absolute-Beginner
www.php.net/gettingstarted would be a nice place to start. once you have crawled through that, feel free to google php tutorials
