PHP条件行计算,php,arrays,Php,Arrays,我有一个数组，我已经显示在一个表中，如下面所示： +-------+-------+-------------------+ | | Sales | Earned by date ($)| | Name | Code |-------+-----+-----+ | | | 1 | 2 | 3 |... end of month +-------+-------+-------+-----+-----+ | Jhon | A |

我有一个数组，我已经显示在一个表中，如下面所示：

+-------+-------+-------------------+

在表的最后一行中，我希望根据包含相同销售代码的行的摘要填写每个日期的总行值

我尝试了以下语法：

    <?php
$data = array(
    "0" => array("name" => "Jhon", "sales_code"=>"A", "1" => 4.5, "2"=>7, "3"=>2),
    "1" => array("name" => "Jhon", "sales_code"=>"B", "1" => 1.5, "2"=>7, "3"=>5),
    "2" => array("name" => "Jhon",  "sales_code"=>"C", "1" => 8.2, "2"=>4, "3"=>4),
    "3" => array("name" => "Ryan", "sales_code"=>"A", "1" => 4, "2"=>6, "3"=>3),
    "4" => array("name" => "Ryan",  "sales_code"=>"B", "1" => 5, "2"=>7, "3"=>2),
    "5" => array("name" => "Ryan",  "sales_code"=>"C", "1" => 2.9, "2"=>9, "3"=>7),
    "6" => array("name" => "Jeny",  "sales_code"=>"A", "1" => 9.1, "2"=>3, "3"=>4),
    "7" => array("name" => "Jeny",  "sales_code"=>"B", "1" => 5, "2"=>5, "3"=>6),
    "8" => array("name" => "Jeny",  "sales_code"=>"C", "1" => 7, "2"=>6, "3"=>3),
    );


    ?>
    <table border="1" width="">
        <tr>
            <th rowspan="2">Name</th>
            <th rowspan="2">Sales code</th>
            <th colspan="3">Earned by date ($)</th>
        </tr>
        <tr>
            <th>1</th>
            <th>2</th>
            <th>3</th>
        </tr>
        <?php
        $a_tot = 0;
        $c_tot = 0;
        $b_tot = 0;
        foreach($data as $row){
            ?>
            <tr>
                <td><?=$row['name']?></td>
                <td><?=$row['sales_code']?></td>
                <td><?=$row['1']?></td>
                <td><?=$row['2']?></td>
                <td><?=$row['3']?></td>
            </tr>
            <?php
            $a_tot += ($row['sales_code'] == "A" ? $row['1'] : 0);
            $b_tot += ($row['sales_code'] == "B" ? $row['2'] : 0);
            $c_tot += ($row['sales_code'] == "C" ? $row['3'] : 0);
        }
        ?>
        <tr>
            <td>TOTAL</td><td>A</td> <td><?=$a_tot?></td> <td><?=$a_tot?></td> <td><?=$a_tot?></td>
        </tr>
        <tr>
            <td>TOTAL</td><td>B</td> <td><?=$b_tot?></td> <td><?=$b_tot?></td> <td><?=$b_tot?></td>
        </tr>
        <tr>
            <td>TOTAL</td><td>C</td> <td><?=$c_tot?></td> <td><?=$c_tot?></td> <td><?=$c_tot?></td>
        </tr>

    </table>

我希望得到如下结果：

另一种选择是，不必硬编码这些组合数字，只需创建这些总数的数组即可。首先创建总数，然后显示它们。换句话说，先把他们分组

谢谢@Ghost，你救了我一天。@HarapanHarefa当然很高兴这个帮助谢谢@Ghost，你救了我一天。@HarapanHarefa当然很高兴这个帮助如果对你有用，请接受答案。谢谢谢谢你的帮助，但是其他人给出了最合适的答案，因为我需要一个支持动态内容的代码，然后在问题中说明！“如果你对你的数据结构了解得更多，你可以让这个表变得更灵活、更健壮。”浪费每个人的时间。如果这对你有用，请接受答案。谢谢谢谢你的帮助，但是其他人给出了最合适的答案，因为我需要一个支持动态内容的代码，然后在问题中说明！“如果你对你的数据结构了解得更多，你可以使这个表变得更灵活、更健壮。”浪费每个人的时间。
