所以我想创建一个函数来返回一个包含这样列表的数组：

和我的职能：

public function getListArray(array $config['place']) {



.....

return $result;

}

Answer 1

这应该这样做

function getListArray($array) {
  static $level = -1;
  static $result = array();
  $level++;
  foreach ($array as $arr) {
    $result[] = str_repeat ('-', $level).$arr['label'];
    if (is_array($arr['childrens'])) {
      getListArray($arr['childrens']);
    }
  }
  $level--;

  return $result;
}
