我从 phpBB 复制了一个函数，以便可以对返回对象进行一些细微的调整。它工作正常，创建组返回组的 ID 等。唯一的问题是当它失败时（在组名存在的情况下）我收到以下错误：
[phpBB Debug] PHP Notice: in file C:/.../phpbb_library.php on line 586: Undefined index: GROUP_NAME_TAKEN
这是我的代码。
构造函数：

define('IN_PHPBB', TRUE);
define('FORUM_ROOT_PATH', Kohana::$config->load('global.FORUM_ABSOLUTE_PATH'));
$phpbb_root_path = (defined('PHPBB_ROOT_PATH')) ? PHPBB_ROOT_PATH : FORUM_ROOT_PATH;
$phpEx = substr(strrchr(__FILE__, '.'), 1);
