Php 将复选框值数组插入数据库，包括未选中的复选框

在下表中，学生从my DB的学生表中选择。对于每个选中的学生，如果该学生缺席，则选中复选框；如果该学生在场，则不选中复选框。稍后提交表单，以便将其插入my DB的考试状态表中

<form method="POST" action="action.php">
<?php
  $query = "SELECT * from student ORDER BY student_name,student_surname";
          $result=mysqli_query($conn,$query);
          if(false===$result)
          {
            printf("error: %s \n",mysqli_error($conn));
          }

          while($row= $result->fetch_assoc()) 
          {
                $studentmatricule = $row['student_matricule'];
                $studentname = $row['student_name'];
                $studentsurname = $row['student_surname'];
?>            
            <div id="studentdiv">
              <label>Matricule</label>
              <input type="text" name="matricule[]" value="<?php echo "$studentmatricule)"; ?>" readonly>

              <label>Name</label>
              <input type="text" name="name[]" value="<?php echo "{$studentname} {$studentsurname}"; ?>" readonly>

              <label > Absent
                  <input type="checkbox" name="absent[]" value="absent" />
              </label>
            </div> <br><br>
        <?php
          }
        ?>
            <input type="submit" name="submit" value="submit">
</form>

你能分享你的学生和考试状态表模式吗？很乐意帮助：）如果有帮助，请投票。若你们要在mysql表中插入多条记录，也可以尝试使用批量插入。我很想升级投票，但我在这个网站上还是新手。我还没有足够的声望去投票。我理解，希望你能清楚我的答案。如果你有任何疑问，请问我
