PHP exercises

Hi folks. A friend of mine is trying to learn PHP. She already knows programming basics, but wants to learn PHP specifically. However, she learns much better with assignments or exercises than just from reading articles or books. The only site I've found so far is PHP Exercises (http://phpexercises.com/), but it of course went offline the day after I found it. Fail! Can anyone recommend other sources for tutorial-based or exercise-based PHP learning? Paid is OK if it's not too expensive and it's worth the money, although free is always preferred. TIA and all that. --Larry Garfield
