I wouldn't use this to teach someone PHP, but it does the job, so that's enough for me.

It actually does not seem great to me, because it is super hard to read.
I would drop most PHP out of it, and just use as close to plain HTML as possible. Alternatively I might refactor it to a point where it reads like english as much as possible. So, basically, there would be no $j and $i, etc.
