    I searched for "recursive function" to find a duplicate, and like every question is about PHP. Why do people think recursive functions are different in PHP? – Michael Mrozek Jun 04 '10 at 05:06

Recursive functions in php are no different than in other languages. It's simply a function that calls itself. There's no real need to show examples of recursion in php because it's just so simple. Take a look at the Wikipedia article. And here's the famous fibonacci numbers example in php.
