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;

}

?>
