On the Make Me Pulse blog, Antoine Ughetto shares a method he came up with to recurse through an array using the SPL method - the RecursiveArrayIterator method.

When we have a multidimensional array we have to make some recursives function to parse it. A simple way to get the keys and the value of this type of array is to use the SPL library of PHP.

A code example is included, parsing through a recursive array to output each of the key/value pairs it contains (and using only about five or six lines of code to do it).
