PHP合併行（多列）

Question

我有這個表：

Material Number | BPM Number | STTPP Number | Qty 

    A | 123 | 1231 | 100 
    A | 123 | 1232 | 200 
    B | 234 | 2341 | 100 
    B | 234 | 2342 | 100 
    C | 432 | 4321 | 100 
    D | 567 | 5671 | 100 
    D | 567 | 5672 | 600 
    D | 568 | 5681 | 300 
    D | 568 | 5682 | 200 
    D | 598 | 5981 | 100 
    D | 598 | 5672 | 90 

，並試圖顯示它看起來就像這樣：

Material Number | BPM Number | STTPP Number | Qty 

    A | 123 | 1231 | 100 
     |  | 1232 | 200 
    B | 234 | 2341 | 100 
     |  | 2342 | 100 
    C | 432 | 4321 | 100 
    D | 567 | 5671 | 100 
     |  | 5672 | 600 
     | 568 | 5681 | 300 
     |  | 5682 | 200 
     | 598 | 5981 | 100 
     |  | 5672 | 90 

到處搜尋，但我發現，他們只合並第一列... 這是我迄今所做的：

<?php 
     $query="SELECT * FROM sttpp_item_list order by material_code"; 
     $proses=mysql_query($query); 
     $i=0; 
     while($data=mysql_fetch_assoc($proses)) 
     { 
      $row[$i]=$data; 
      $i++; 
     } 
     foreach($row as $cell) 
     { 
      if(isset($total[$cell['material_code']]['quantity_dely'])) 
      { 
       $total[$cell['material_code']]['quantity_dely']++; 
      } 
      else 
      { 
       $total[$cell['material_code']]['quantity_dely']=1; 
      }  
     } 
     echo "<table border=\"1\"> 
     <tr> 
      <th>Material Number</th> 
      <th>BPM Number</th> 
      <th>STTPP Number</th> 
      <th>STTPP Number</th> 
     </tr>"; 
     $n=count($row); 
     $cekmaterial_code=""; 
     for($i=0;$i<$n;$i++) 
     { 
      $cell=$row[$i]; 
      echo '<tr>'; 
      if($cekmaterial_code!=$cell['material_code']) 
      { 
       echo '<td' .($total[$cell['material_code']] 
       'quantity_dely']>1?' rowspan="' . 
       ($total[$cell['material_code']]['quantity_dely']).'">':'>') 
       .$cell['material_code'].'</td>'; 
       $cekmaterial_code=$cell['material_code']; 
       } 
       echo "<td>$cell[bpm_number]</td><td>$cell[quantity_dely] 
       </td>"; 
       echo "</tr>"; 
       } 
       echo "</table>"; 
     ?> 

此代碼資源ult：

材料號| BPM編號| STTPP號碼|數量

A | 123 | 1231 | 100 
     | 123 | 1232 | 200 
    B | 234 | 2341 | 100 
     | 234 | 2342 | 100 
    C | 432 | 4321 | 100 
    D | 567 | 5671 | 100 
     | 567 | 5672 | 600 
     | 568 | 5681 | 300 
     | 568 | 5682 | 200 
     | 598 | 5981 | 100 
     | 598 | 5672 | 90 

任何建議？請幫忙...

你的代碼不完整，但我會盡力解決。你只需要像$cell['material_code']那樣檢查$cell['bpm_number']。

$cekmaterial_code = ""; 
$bpm_number = ""; 
for (...) { 
... 
    if ($bpm_number !== $cell['bpm_number']) 
    $bpm_number = $cell['bpm_number']; 
    echo "<td>$cell[bpm_number]</td><td>$cell[quantity_dely</td>"; 
    } else { 
    echo "<td></td><td>$cell[quantity_dely]</td>"; 
    } 
.. 
}
