learning PHP from scratch

Hi, I am teaching a fellow worker PHP. He is, like other 'students' I had working on a small project with database interaction. This approach worked pretty well with previous people i teached PHP, but they already had some sort of programming background. This guy hasn't. I find that he has some difficulties picking it up. And I have some difficulties to further help him. Communication somewhat gets stuck, since he does not know the basic concepts and terminology. Does anybody have ideas or suggestions how to teach PHP to someone without any previous programming experience? Easy documents and tutorials dealing with the basic concepts and terminology? Any help appreciated. Kind regards, Raphael Steenbergen
