A while back I found an Oreilly website that has a ton of awesome php tutorials that I have used many times. The site, OnLAMP PHP Foundations, is a collection of a bunch of different php tutorials dealing with everything from an intro to php to object oriented programming in php.
Here's the link: http://www.onlamp.com/pub/ct/29
Hopefully it's alright that I posted a link to this collection of tutorials in this forum, not sure if this is a place that's only for direct access to tutorials.
If it is alright maybe we could even turn this thread into a sticky and people could contribute their favorite php resource centers.
