MySQL，PHP和表格數據

我有一個半複雜的（不是真的，但它不是最簡單的兩種）數據庫結構：MySQL，PHP和表格數據

appointments = id，teacher_id，child_id，slot

child = id， parent_id，name，form

parent = id，name，contact_details

teacher = id，name，subject

slot = id，time

因此，我一直在使用一些多聯接SELECT語句來獲取我所需要的數據，如：

SELECT 
DISTINCT ((c.id +150) *1055) AS reference_number, 
p.name AS parent_name, 
c.name AS child_name, 
c.form AS child_form 
FROM appointments AS a 
INNER JOIN child AS c ON a.child_id = c.id 
INNER JOIN parent AS p ON c.parent_id = p.id

我想要做的是生成一張表，其中slots是一個軸，而teachers是另一個軸，其中在該時間段內爲該教師預訂的孩子的名稱作爲實際數據。

的slot表看起來像這樣：

SQL query: SELECT * FROM `slots` LIMIT 0, 30 ; 
Rows: 30 

id time 
1 2012-03-15 16:00:00 
2 2012-03-15 16:05:00 
3 2012-03-15 16:10:00 
4 2012-03-15 16:15:00 
5 2012-03-15 16:20:00 
6 2012-03-15 16:25:00 
7 2012-03-15 16:30:00 
8 2012-03-15 16:35:00 
9 2012-03-15 16:40:00 
10 2012-03-15 16:45:00 
11 2012-03-15 16:50:00 
12 2012-03-15 16:55:00 
13 2012-03-15 17:00:00 
14 2012-03-15 17:05:00 
15 2012-03-15 17:10:00 
16 2012-03-15 17:15:00 
17 2012-03-15 17:20:00 
18 2012-03-15 17:25:00

的appointments表看起來像這樣幾個條目後：

id teacher_id child_id slot 
1 1 1 3 
2 2 1 5 
3 1 3 2 
4 2 3 6 
5 1 4 4 
6 2 4 7 
7 1 5 1 
8 2 5 9 
9 1 6 8 
10 2 6 3

我試着用PHP來把東西在一起，但它真的傷了我的頭！

任何人都可以推薦一個解決方案，而不使用外部腳本？

編輯按要求這裏是我想要達到一個小的屏幕截圖。我在Excel中這樣做了，但顯然，按照主題，我想在PHP/HTML中使用它。

Tabular Data?

由於提前，

感謝您的建議@MarcusAdams - 我現在已經這麼做了。 – dunc 2012-03-05 21:00:26

關閉我的頭頂，我會嘗試這樣的事情。第一位是僞代碼。這應該會生成一個表，其中包含第一列中的所有教師姓名，然後是每個時間段的列，然後是已預約約會的單元格中的子女姓名。

$appointments =

SELECT DISTINCT （（c.id 150）* 1055）AS REFERENCE_NUMBER， p.name AS PARENT_NAME， c.name AS CHILD_NAME， c.form AS child_form，一個.id AS任命， a。時隙AS slotID用於與約會AS一 INNER JOIN孩子爲C ON a.child_id = c.id INNER JOIN父爲P ON c.parent_id = p.id

$teachers = SELECT ID，老師教師

$slots = SELECT ID，時間從插槽

找那些到關聯數組所以你必須$appointments$teachers$slots（你可以添加該代碼）

<?php 

// simply add a blank child element to each slot 
foreach($slots as $slotKey => $slot) 
{ 
    $slots[$slotKey]['child'] = ''; 
} 

// now add the full empty slot list to all teachers 
foreach($teachers as $key => $teacher) 
{ 
    $teachers[$key]['appointments'] = $slots; 
} 

// now to fill in the child names into the teachers slots where they have an appointment 
foreach($teachers as $teacher) 
{ 
    foreach($teacher['slots'] as $slotKey => $slot) 
    { 
     foreach($appointments as $appointment) 
     { 
      if($slot['id'] == $appointment['slotid']) 
      { 
       $teacher[$key][$slotKey]['child'] = $appointment['child_name']; 
      } 
     } 
    } 
} 

// now lets output the HTML table 
?> 

<table> 

    <tr> 
     <th>Teacher</th> 
     <?php foreach($slots as $s): ?> 
      <th><?php echo $s['time']; ?></th> 
     <?php endforeach; ?> 
    </tr> 

    <?php foreach($teachers as $t): ?> 

     <tr> 

      <td><?php echo $t['name']; ?></td> 
      <?php foreach($t['slots'] as $slot): ?> 
       <td><?php echo $slot['child_name']; ?></td> 
      <?php endforeach; ?> 

     </tr> 

    <?php endforeach; ?> 

</table>
