Updated; used to test for input as an array, should have been a string, added some validation of the
input while I was at it. Enjoy.
<?php
/*---------- Directory Tree to Array ----------//
Takes base directory, returns an associative array
containing each directory name as an associative key
and each file as an indexed entry in the appropriate
directory.
If no path is provided, it uses the current directory
If $style == 1, it will return a sorted, non-associative
array

Use it as much as you like for whatever
For my own entertainment, please let me know if you do
