            else if($Rscore == '80' or $Rscore=='2' or $Rscore=='3'){
                $rID =$this->lawmodel->getID($row->requestedID);

                echo $row->username." got the correct answer";
                }
            }
        }
    }

我在这个ajax调用中遇到了问题..

我对ajax调用的目的是它总是会检查数据库是否有更新...当有更新时..会显示更新。

我意识到，因为我把这个ajax调用..有一段时间它会突然退出我的会话。我无法找到导致此错误的原因。
