分组亚组（使用PHP循环）

Question

我曾经读过一个关于“在PHP分组如何分组结果”（在这个论坛）的问题。我有一个问题几乎与问题相同。

我有一个MySQL表是这样的：

+----------+----------+----------+--------------+-------+-------+--------+ 
| type |  ID | customer | address | bill |service| total | 
+----------+----------+----------+--------------+-------+-------+--------+ 
|water  |A1  |jhon  |Samrat street |100 |50  |150  | 
|electric |A1  |jhon  |Samrat street |30  |15  |45  | 
|electric |A2  |ana  |zero street |20  |10  |30  | 
|water  |A3  |billy  |west street |40  |60  |100  | 
+----------+----------+----------+--------------+-------+-------+--------+ 

我想在通知函显示表中的记录，像这样：

JHON（A1）

Samrat的街道

+---------+-------+----------+---------+ 
|type  |bill |service |total | 
+---------+-------+----------+---------+ 
|water |100 |50  |150  | 
|electric |30  |15  |45  | 
+---------+-------+----------+---------+ 
|     grand total|600  | 
+----------------------------+---------+ 

ANA（A2）

零街

+---------+-------+----------+---------+ 
|type  |bill |service |total | 
+---------+-------+----------+---------+ 
|electric |20  |10  |30  | 
+---------+-------+----------+---------+ 
|     grand total|30  | 
+----------------------------+---------+ 

比利（A3）

西街

+---------+-------+----------+---------+ 
|type  |bill |service |total | 
+---------+-------+----------+---------+ 
|water |40  |60  |100  | 
+---------+-------+----------+---------+ 
|     grand total|100  | 
+----------------------------+---------+ 

实际上，我提出用FPDF和笨的外观。但我相信它是PHP网页制作，因为我只是想知道如何使使用的foreach方法（PHP纯笨或）循环的过程。

我希望有人能帮助我。 谢谢你的好意.. ^^”

试试这个

$query = mysql_query('SELECT * FROM table GROUP BY ID'); 

foreach (mysql_fetch_object($query) as $row){ 

    $data .= '<div>'; 

    $data .= '<p>' . $row->customer . '(' . $row->ID . ')' . '</p>'; 

    $data .= '<p>' . $row->address . '</p>'; 

    $data .= '<table>'; 

    $query1 = mysql_query('SELECT * FROM table WHERE ID = ' . $row->ID . ' AND customer = "' . $row->customer . '" AND address = "' . $row->address . '"'); 

    $data .= ' 
       <tr> 
        <td>type</td> 
        <td>bill</td> 
        <td>service</td> 
        <td>total</td> 
       </tr> 
      '; 

    $total = 0;    //variable initialized for grand total  
    foreach(mysql_fetch_object($sql1) as $row1){ 

    $data .= ' 
       <tr> 
        <td>' . $row->type . '</td> 
        <td>' . $row->bill . '</td> 
        <td>' . $row->service . '</td> 
        <td>' . $row->total . '</td> 
       </tr> 
      '; 

    $total += $row->total;  //adding the total amount for the grand total 

    } 

    $data .= ' 
       <tr> 
        <td colspan="2" align="right">Grand Total</td> 
        <td colspan="2" align="right">' . $total . '</td> 
       </tr> 
      ';   //This displays the grand total 

    $data .= '</table>'; 

    $data .= '</div>'; 

}
