";
         
        $id=parent::dbconn();
        $result=mysql_query("select * from table01",$id);
        while($row=mysql_fetch_array($result)){
            echo "Numbers:".$row['number']."\tName:".$row['name']."
";
        }
    }
     
    function secure_handler(){
        if($_SESSION['name']=="Wangzy"){
            $this->handled_event();
        }else{
            echo "Sorry {$_SESSION['name']} you are not authorized!";
        }
    }
}
