Example to only return directories that are a specified depth in a tree:

<?php
function directory_mapper($path)
{
   
$maxDepth = 3;
   
$minDepth = 3;
   
$iterator = new RecursiveIteratorIterator(
        new
RecursiveDirectoryIterator($path, RecursiveDirectoryIterator::SKIP_DOTS),
       
RecursiveIteratorIterator::SELF_FIRST,
       
RecursiveIteratorIterator::CATCH_GET_CHILD// Ignore "Permission denied"
   
);
   
$iterator->setMaxDepth($maxDepth);

   
$paths = array($path);
    foreach (
$iterator as $path => $dir) {
        if (
$iterator->getDepth() >= $minDepth) {
            if (
$dir->isDir()) {
               
$paths[] = $path;
            }
        }

    }
   
array_shift($paths);
    return
$paths;
}
?>
