如何使用php汇总表数据值但不选择mysql表

mysql_query("SELECT  * FROM pay_detec  WHERE (`nic_num` LIKE '%".$query."%') OR (`cust_name` LIKE '%".$query."%')"); 
if(mysql_num_rows($raw_results) > 0)
{
while($results = mysql_fetch_array($raw_results))
{ 

echo "<tr align='CENTER' bgcolor='FBE946'>

<td height='25px'>".$results['cust_name']."</td> <td>".$results['nic_num']."</td><td>".$results['acc_num']."</td><td>".$results['due_date']."</td>
<td>".$results['loan']."</td><td>".$results['due_months']."</td> <td>".$results['blanc_due']."</td><td>".$results['month_pay']."</td>
<td >".$results['payment']."</td><td>".$results['INTRST']."<td bgColor=red colSpan=0>".$results['short']."</td><td>".$results['othr_chrg']."</td><td>".$results['DELAY_CHRG']."</td><td>".$results['ADVNC']."</td><td>".$results['ttl']."</td><td>".$results['blanc2']."</td></tr>" ;
}

Answer 1

就像Honza所说，当你循环遍历行时，使用变量来总结。你也可以使用mysqls WITH ROLLUP和你的组（https://dev.mysql.com/doc/refman/5.0/en/group-by-modifiers.html）

我还要看看如何保护你的SQL作为上面的查询，如果你正在使用它，将$ query作为用户输入，将让你对SQL注入开放。

示例：

$totalCol = 0;
    mysql_query("SELECT  * FROM pay_detec  WHERE (`nic_num` LIKE '%".$query."%') OR (`cust_name` LIKE '%".$query."%')"); 
    if(mysql_num_rows($raw_results) > 0)
    {
        while($results = mysql_fetch_array($raw_results))
        { 
            $totalCol += $results['a_col'];
            echo "<tr align='CENTER' bgcolor='FBE946'>
            <td height='25px'>".$results['cust_name']."</td> <td>".$results['nic_num']."</td><td>".$results['acc_num']."</td><td>".$results['due_date']."</td>
            <td>".$results['loan']."</td><td>".$results['due_months']."</td> <td>".$results['blanc_due']."</td><td>".$results['month_pay']."</td>
            <td >".$results['payment']."</td><td>".$results['INTRST']."<td bgColor=red colSpan=0>".$results['short']."</td><td>".$results['othr_chrg']."</td><td>".$results['DELAY_CHRG']."</td><td>".$results['ADVNC']."</td><td>".$results['ttl']."</td><td>".$results['blanc2']."</td></tr>";
        }
        /* row for totals */
    }
