<?php
/* The below function will list all folders and files within a directory
It is a recursive function that uses a global array.  The global array was the easiest 
way for me to work with an array in a recursive function
*This function has no limit on the number of levels down you can search.
*The array structure was one that worked for me.
ARGUMENTS:
$startdir => specify the directory to start from; format: must end in a "/"
$searchSubdirs => True/false; True if you want to search subdirectories
$directoriesonly => True/false; True if you want to only return directories
$maxlevel => "all" or a number; specifes the number of directories down that you want to search
$level => integer; directory level that the function is currently searching
