  $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;
}
