Question

我用PHP编写代码（如下所列），但面临一个小问题......

<html>
<head>
<title> trans </title>
<body>
<style>
table, th, td {
border: 1px solid black;
width: 700px;
margin: auto;
}
</style>
<?php

$con = mysqli_connect('localhost', 'root', '');
if(!$con)
{
    die("not ok");
}

mysqli_select_db($con,"uoh");  


$q1 = "SELECT * FROM student_record INNER JOIN degree_plan ON
 student_record.course_number = degree_plan.course_number 
 INNER JOIN courses ON student_record.course_number = 
 courses.course_number where student_record.id  = 201102887 AND degree_plan.major='COE'";

$result = mysqli_query($con , $q1 ) ;
if($result){
   echo "<table>";
   echo "<tr>";
   echo "<th>courses</th>";
   echo "<th>terms</th>";
   echo "<th>grades</th>";
   echo "<th>CRD</th>";
   echo "</tr>";
while($row = mysqli_fetch_array($result))
{

   echo "<tr>";
   echo "<td>" . $row["code"]. "</td>";
   echo "<td>" . $row["term_no"]. "</td>";
   echo "<td>" . $row["grade"]. "</td>";
   echo "</tr>";
}
echo "</table>";
   }

?>

</body>
</html>

当我运行代码时，我看到以下输出：

---------------------------------------
|   courses    |   terms  |   grades  |
---------------------------------------
|   CHEM 101   |     1    |     A     |
---------------------------------------
|   ENGL 101   |     1    |     C+    |
---------------------------------------
|   PE 101     |     1    |     B     |
---------------------------------------
|   PHYS 101   |     1    |     F     |
---------------------------------------
|   ENGL 102   |     2    |     B+    |
---------------------------------------
|   PE 101     |     2    |     B     |
---------------------------------------
|   PHYS 102   |     2    |     D+    |
---------------------------------------
|   MATH 201   |     3    |     A     |
---------------------------------------
|   COE 200    |     3    |     B     |
---------------------------------------

但我不想那样。我希望术语细胞成为一体，如下所示：

---------------------------------------
|   courses    |   term   |   grade   |
---------------------------------------
|   CHEM 101         1          A     |
|   ENGL 101                    C+    |
|   PE 101                      B     |
|   PHYS 101                    F     |
---------------------------------------
|   ENGL 102         2          B+    |
|   PE 101                      B     |
|   PHYS 102                    D+    |
---------------------------------------
|   MATH 201         3          A     |
|   COE 200                     B     |
---------------------------------------

或以任何其他方式不允许术语重复，我的意思是：将具有相同术语的课程组合在一起。

试试这段代码，

function test ($id)
{ 
 echo $id ."<br>";
 echo $this->input->post('name');    
}
