Answer 1

You can use q.* and a.center uisng alias center_name

    $qry="select q.*, a.center center_name from teacher_profile AS q 
            left join center AS a on a.id = q.centerId
           ORDER BY q.id DESC";
        $result=mysqli_query($mysqli,$qry);

you can refere the the column using index center_name

       echo $row['center_name'];

Answer 2

On the query, select statement you can specify which columns you want.

see example

$qry="
SELECT
   center.name, teacher_profile.*
FROM 
    teacher_profile
left join center on teacher_profile.id = center.centerId
ORDER BY 
    teacher_profile.id DESC
";
$result=mysqli_query($mysqli,$qry);
