How can I convert row data to column in PHP

Question

I have an academic table that contains data.

eg:

level	percentage
Degree	50
Diploma	70
Post Diploma	67

This is my code, but not working:

<table>
    <tr>
        <th>Degree</th>
    <th>Diploma</th>
       
    $stmtc = $conn->prepare("SELECT 
    MAX(CASE WHEN level = 'Degree' THEN percentage END) AS $degree,
    MAX(CASE WHEN level = 'Diploma' THEN percentage END) AS $diploma 
    FROM tbl_academic_qualification WHERE member_no = '$emp_id'");
    $stmtc->execute();
        $resultc = $stmtc->fetchAll();
        foreach($resultc as $rowc){
            $degree = $rowc['percentage'];
            $diploma = $rowc['percentage'];
                                                                
    ?>
    
    <tr>
        <td><?php echo "$degree"; ?></td>
        <td><?php echo "$diploma"; ?></td>
        </tr>

</table>

I want to display like this:

Degree	Diploma	Post Diploma
50	70	67
