As it's still unclear if you're trying to read from some given structure (html-dom) or from the given string as plain text, I assumed it's the string you're trying to parse. If so, try:

      if (!isset($parent[$key])) {
        $parent[$line] = array();
        break;

    }
  }

  // return
  return $result;
}

print_r(helper($list));
