    }catch(PDOException $e){
        echo '数据库连接失败:'.$e->getMessage();
        exit;    
    }
    
    $query = "UPDATE contactInfo SET phone='15801680168' where name='高某某'"; 
    //使用exec()方法可以执行INSERT、UPDATE和DELETE等
    $affected = $dbh->exec($query);       
    
    if($affected){          
        echo '数据表contactInfo中受影响的行数为:'.$affected;
