如何在php mysql中獲取並顯示這些數據？

Question

我有問題表和主題表和問題表包含在線考試的主題明智的問題。

我需要提取主題名稱作爲標題的明智問題，並以主題明智的序列號顯示所有問題，例如：數學：Q1，Q2，Q3 英語：Q1，Q2，Q3等。 如何在php和mysql中實現它。問題表和主題表如下。

問題樣本數據在下面給出

<?php 
    require_once 'config.php'; 
    //$con = mysqli_connect("localhost","root","","database_name"); 
    $query1 = "SELECT q.q_id,q.setq_no, q.qtext_eng, s.sub_id, s.sub_name 
    FROM question q 
    INNER JOIN subject s ON s.sub_id = q.sub_id 
    INNER JOIN questionset qs ON qs.qset_id = q.qset_id 
    WHERE qs.qset_id =2 ORDER BY s.sub_id"; 
    ?> 
<table class="table table-bordered"> 
<thead> 
<tr> 
    <th>Q.No</th> 
    <th>Q Set number</th> 
    <th>Q text eng</th> 
</tr> 

<?php 
$result1 = mysqli_query($link,$query1); 

while($row1 = mysqli_fetch_array($result1)) 
{ 
$subID = $row1['sub_id']; 
    $subName = $row1['sub_name']; 
    ?> 
    <h2><?php echo "$subName" ?></h2> 

<?php 
    error_reporting(0); 


    $sno++; 
    $qSet = $row1['setq_no']; 
    $qEng = $row1['qtext_eng']; 

?> 
<tr> 
    <td><?php echo $sno; ?></td> 
    <td><?php echo $qSet; ?></td> 
    <td><?php echo $qEng; ?></td> 
</tr> 
</tbody> 
</table> 
    <?php 
    } 
?>

我包括一些來自question表在這裏你列的，你可以添加其他同樣的方式

<?php 
$con = mysqli_connect("localhost","root","","database_name"); 

$query1 = "SELECT q.q_id,q.setq_no, q.qtext_eng, s.sub_id, s.sub_name 
FROM question q 
INNER JOIN subject s ON s.sub_id = q.sub_id 
INNER JOIN questionset qs ON qs.qset_id = q.qset_id 
WHERE qs.qset_id =2 ORDER BY s.sub_id"; 

$presubID = 0; 

<table class="table table-bordered"> 
while($row1 = mysqli_fetch_array($result1)) 
{ 
    $subID = $row1['sub_id']; 
    if($subID != $presubID){ 
    $subName = $row1['sub_name']; 
    <h2><?php echo "$subName" ?></h2> 
    $sno=0; 

     <thead> 
     <tr> 
      <th>Q.No</th> 
      <th>Q Set</th> 
      <th>Q text eng</th> 
     </tr> 
     </thead> 
    } 
    $presubID = $subID; 

    $sno++; 
    $qSet = $row1['setq_no']; 
    $qEng = $row1['qtext_eng']; 

    <tr> 
    <td><?php echo $sno; ?></td> 
    <td><?php echo $qSet; ?></td> 
    <td><?php echo $qEng; ?></td> 
    </tr> 

<?php 
    } 
?> 
</table>
