note 57804 added to ref.strings

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.
