Well, if you do a count of the root, you ought to get the amount of
numbers in there, and, with that number of the last item, access that
array, do a count() on that, get the last item, and so forth and so on,
you could write a small recursive function here to call itself with each
new child, getting the last item, down into the structure until X level.

Not sure if there's a PHP native function for doing this, though.
Perhaps someone else knows. If nothing else, try this way.
