如何在php mysql中获取并显示这些数据？

Question

我有问题表，主题表和问题表包含在线考试的主题明智问题。

我需要以主题名称作为标题来获取主题明智的问题，并以主题序列号显示所有问题，例如：数学：Q1，Q2，Q3 英语：Q1，Q2，Q3等。 如何在php和mysql中实现它。问题表和主题表如下。

问题样本数据如下：

<?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
   }
 ?>

我在这里列出了question表中的一些列，您可以添加其余的相同方式

<?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>
