我有这张表,它只是减去从 recv 移动销售的手机,而不是显示在平衡手机中,还加上旧行余额和新行。
|Received Mobiles |Mobile i have sold | Balance |
|6 |1 | 5
|3 |2 | 6
|4 |2 | 8 ----------> total mobiles i have
但我想反转(计算从最后开始)这个结果并想这样显示,因为我想在顶部看到新记录
|Received Mobiles |Mobile i have sold | Balance |
|6 |1 | 8 ----------> total mobiles i have
|3 |2 | 3
|4 |2 | 2 <------- plus with recv mob 3 then - sold mob
我在写这个
while ($fetch = mysql_fetch_array($query)) {
$recvtotal += $fetch[recv];
$soldtotal += $fetch[sold];
$balancing += $fetch[recv]-$fetch[sold];
echo "<tr>";
echo "<td>" . $fetch[brand] . "</td>";
echo "<td>" . $fetch[recv] . "</td>";
echo "<td>" . $fetch[sold] . "</td>";
echo "<td>" . ($balancing) . "</td>";
echo "</tr>";
}
