Question

我不确定如何制定问题的标题。我有这个数组：

Array
(
    [0] => Array
        (
            [account] => 700000
            [percent] => 0.0000
            [amount] => 3
        )

    [1] => Array
        (
            [account] => 705010
            [percent] => 6.0000
            [amount] => 4.7
        )

    [2] => Array
        (
            [account] => 700000
            [percent] => 0.0000
            [amount] => 93
        )

    [3] => Array
        (
            [account] => 700000
            [percent] => 6.0000
            [amount] => 9.43
        )

    [4] => Array
        (
            [account] => 700000
            [percent] => 12.0000
            [amount] => 35.72
        )

    [5] => Array
        (
            [account] => 700000
            [percent] => 21.0000
            [amount] => 8.26
        )

    [6] => Array
        (
            [account] => 705300
            [percent] => 21.0000
            [amount] => 8.26
        )

    [7] => Array
        (
            [account] => 705300
            [percent] => 21.0000
            [amount] => 57.86
        )

)

如果帐户和百分比都匹配，我需要找到一种方法来累加金额。

我应该遍历每个数组并执行“if”检查以查看帐户和百分比是否已经存在，然后加上金额，否则保持原样？

这是否有php功能？

我一直在研究array_unique，但我不太确定如何做到这一点。

一如既往，感谢任何帮助！

你可以使用这样的东西。它将生成一个嵌套结构，似乎可能更容易使用。

foreach ($array as $item) {
    $grouped[$item['account']][$item['percent']] += $item['amount'];
}

如果你需要把它们放回原来的格式，那就基本上做相反的操作

foreach ($grouped as $account => $percents) {
    foreach ($percents as $percent => $amount) {
        $new_array[] = array(
            'account' => $account, 'percent' => $percent, 'amount' => $amount);
    }
}

如果存在2个值，则数组中数量的总和
