Tutorials:
www.pixel2life.com (go to PHP category)
www.good-tutorials.com (go to PHP category)
www.nettuts.com has php tutorials occasionally
www.talkphp.com is a great site(well duuh). There's tutorials in the article section, and also there are tutorials in advanced php category of the forum, even in the basic php category of the forum. I've posted some tutorials here on the advanced php section.

Talkphp is also a great resource when you've hit an error you can't figure out on your own - just post it here and someone will reply.

For looking up functions, I'd just go with www.php.net - it's by far the best site with information about that. In top right corner, just search your function.

Anyways, this was some information about resources, hope this helps
Also - we're quite offtopic now, so if you need more information about phpresources I suggest you open an own thread in general, or just PM someone(like me for example xD)
