Because writing articles is typically such a one-way medium, I often forget that all the energy I have poured into illustrating programming concepts in PHP actually ends up helping people.

Got this nice note in my inbox today:

I was looking for a good tutorial on recursion for displaying directory subtrees and this was a really well explained tutorials, nice work.[sic]

From “David”, age fifteen, Ireland. You don’t have to be young or Irish to learn more about recursion in PHP through this article. Always great to get feedback from real people putting this stuff to use.
