PHP輸出重複值的foreach

Question

我有一個數據庫（MySQL的）表像

id | assign_id | rights | party 
---+-------------+------------+--------- 
1 |5   | 12  | xyz 
2 |5   | 3   | xyz 
3 |6   | 14  | abc 
4 |6   | 5   | abc 

現在，我想讓我的表格格式輸出以這種方式使用PHP的foreach

| assign_id | rights | party 
---+-------------+------------+--------- 
    |5   | 12,3  | xyz 

    |6   | 5,14  | abc 

的表結構是

     <th> Assign ID.  </th> 
         <th> Party Name  </th> 
         <th> rights</th> 
        </tr> 

        </thead> 
        <tbody> 

        <?php if(is_array($aryAssign)) { 
         $cntuser=1; 
         foreach($aryAssign as $aryAssign){ ?> 

        <tr> 

         <td> <?php echo $aryAssign['assign_id']; ?> </td> 
         <td> <?php echo $aryAssign['party']; ?> </td> 
        <td> <?php echo $aryAssign['rights']; ?> </td> 
               </tr> 
        <?php } } ?> 

        </tbody> 
       </table>

爲什麼你不使用GROUP_CONCAT：

SELECT assign_id, party, GROUP_CONCAT(rights) 
FROM mytable 
GROUP BY assign_id, party
