Question

很抱歉，我看到了多个类似的解决方案，但我无法在我的情况下实施它们。我试过检查是否在sum之前存在值，但是它给了我真正的值并且无法添加它的实际值。使用波纹管代码，只要循环运行并给出错误的总和值，它就会重复相同的值。请指正。

我想通过匹配键将数组值添加到单个数组中。

我有这个阵列......

Array(
[0] => Array
    (
        [Customer] => Array
            (
                [created_by] => 3
                [amount] => 475
            )

    )

[1] => Array
    (
        [Customer] => Array
            (
                [created_by] => 5
                [amount] => 199
            )

    )

[2] => Array
    (
        [Customer] => Array
            (
                [created_by] => 1
                [amount] => 199
                [refund_amount] => 200
                [upgrade_amount] => 199
            )

    )

[3] => Array
    (
        [Customer] => Array
            (
                [created_by] => 1
                [amount] => 199
            )

    )

[4] => Array
    (
        [Customer] => Array
            (
                [created_by] => 4
                [upgrade_amount] => 199
            )

    )

）我正在寻找像这样的结果......

Array(
[3] => Array
    (
        [sale] => 475
        [refund] => 0
        [upgrade] => 0
    )

[5] => Array
    (
        [sale] => 199
        [refund] => 0
        [upgrade] => 0
    )

[1] => Array
    (
        [sale] => 398
        [refund] => 200
        [upgrade] => 199
    )

[4] => Array
    (
        [sale] => 0
        [refund] => 0
        [upgrade] => 199
    )

）

我使用此代码获取结果....

   foreach($records as $y_key => $y_value){
            //print_r($y_value);
            if(!isset($top_performer[$y_value['Customer']['created_by']])){
                $top_performer[$y_value['Customer']['created_by']]['sale'] = 0;
                $top_performer[$y_value['Customer']['created_by']]['refund'] = 0;
                $top_performer[$y_value['Customer']['created_by']]['upgrade'] = 0;
            }
             $top_performer[$y_value['Customer']['created_by']]['sale']+= $y_value['Customer']['amount'];
             $top_performer[$y_value['Customer']['created_by']]['refund']+= $y_value['Customer']['refund_amount'];
             $top_performer[$y_value['Customer']['created_by']]['upgrade']+=$y_value['Customer']['upgrade_amount'];

        }

您的代码看起来不错，您只需要检查数组元素是否存在

   foreach($records as $y_key => $y_value){
            if(!isset($top_performer[$y_value['Customer']['created_by']])){
                $top_performer[$y_value['Customer']['created_by']]['sale'] = 0;
                $top_performer[$y_value['Customer']['created_by']]['refund'] = 0;
                $top_performer[$y_value['Customer']['created_by']]['upgrade'] = 0;
            }
             $top_performer[$y_value['Customer']['created_by']]['sale'] += isset($y_value['Customer']['amount']) ? $y_value['Customer']['amount'] : 0;
             $top_performer[$y_value['Customer']['created_by']]['refund'] += isset($y_value['Customer']['refund_amount']) ? $y_value['Customer']['refund_amount'] : 0;
             $top_performer[$y_value['Customer']['created_by']]['upgrade'] += isset($y_value['Customer']['upgrade_amount']) ? $y_value['Customer']['upgrade_amount'] : 0;
    }

如何按图表的键对数组值求和？
