PHP teaching supplements?

I have a friend who has wanted to learn PHP for a while. She is very bright and picks things up quickly, so what I have been able to show her has helped quite a bit.

I have been coding in PHP for ten years or so. The problem is that I can answer most any questions she has, but I do not have time to sit down and put together a line of projects increasing in complexity for her to build and learn from.

What I am looking for is a site/blog/etc which has an open/free base curriculum of sorts, that has projects going from simple to difficult, that teach coding开发者_JAVA技巧 concepts and introduce sections of the language in an easy to consume manner.

It doesn't need to have a lot of explanation, or hand holding. I can do that. Just projects with goals, requirements, etc.

Anyone aware of something like this?

Thanks in advance!
