现在我正在使用以下步骤来反序列化这个数组：
$user_group_query = $this->db->query("SELECT permission FROM " . DB_PREFIX . "user_group WHERE user_group_id = '" . (int)$user_query->row['user_group_id'] . "'");
$permissions = unserialize($user_group_query->row['permission']);
但我收到错误消息：
Notice: unserialize() [function.unserialize]: Error at offset 0 of 7081 bytes in D:\wamp\www\UI\system\library\user.php on line 23
为什么我收到这个错误？？？如果有人遇到类似的问题，请帮助我...
