Question

我们有一个表格，其中包含学生被分配到的所有课程和级别。此表名为＆＃39; tbl_assignedclass ＆＃39;包含studentID，programID，levelID和semesterID

我需要在完成三个学期的相同课程和水平后显示学生的统计数据，如果他再学习不同的课程和水平，则需要再次显示。

    <?php
    $query="SELECT * FROM `tbl_assignedclass` where student_id ='1' ";
    $result_assign = $conn->query($query);
    while($row_assign  = $result_assign->fetch_assoc())
    {
        ?>  
        //I want to display the following data
        <div>
          statistics for studentID,<br /> 
           Semester Name - Program Name - level Name <br>
        </div>
   <?php }
  ?>

<?php
$display = '';
$dbc = mysqli_connect("", "", "", "");
if (mysqli_connect_errno()) {
    echo mysqli_connect_error();
    exit();
}
    $query = "SELECT * FROM tbl_assignedclass WHERE student_id='1'";
        $result = mysqli_query($dbc, $query);
        if($result){
            while($row = mysqli_fetch_assoc($result)){  
                $id = $row['id'];
                $name = $row['name'];
                $email = $row['email'];
                $display .= 'ID: '.$id.' NAME: '.$name.' EMAIL: '.$email.'<br>'; 
            }
         }else{$display = 'NO RESULTS';}
echo $display;
?>
