If you are looking for a reasonably comprehensive php tutorial then check out hudzilla. Now it’s a little tough going in places but if you work through it systematically you should get somewhere. I’m still green but I’m working at it. What I like about it is that it assumes no php knowledge and takes you through further than other online php tutorials I have seen.

If you know of any better ones, be sure to let me know because I’m still looking.
