Well, first off, we have some general PHP tutorials - everything from an introduction to some of the PHP stuff to some more advanced things with databases and the like. Be sure to check these tutorials out if you are new to the PHP world.
Also today, we have yet another PHPNuke tutorial care of PHPNewbie. And it also seems that our column has attracted the attention of the guys over at PHPNuke.org because even they posted about it. whee!
