这是我的功能：

public function getFeedback($p_iUserid) {

    include("Connection.PHP"); //oPEn db

    try
    {
        $sql = "select DiaryOpmerkingen,DiaryDoctorcomment From tblDiary 
                WHERE fk_UserId = ".$p_iUserid."
                AND DiaryDay = '".$this->Day."';";
        $rResult = MysqLi_query($link,$sql);
        return $rResult;
    }
    catch(Exception $e)
    {
        // no connection database
        $Feedback = $e->getMessage();
    }
    MysqLi_close($link);
}

这就是我现在设法调用该函数的方法.但它只适用一次：

if(MysqLi_num_rows($FeedbackPatient) > 0)
                    {
                        while($oUser = MysqLi_fetch_assoc($allUsers))
                        {
                            echo $oUser['DiaryOpmerkingen'];
                        }
                    }

我希望有人能帮帮忙！
不管怎么说,还是要谢谢你.
