数组总和在数组PHP

Question

嗨，请帮忙。如何总结这个数组

Array
(
    [975] => Array
        (
            [0] => Array
                (
                    [0] => 79.35
                    [1] => 14.28
                )
            [1] => Array
                (
                    [0] => 79.35
                    [1] => 14.28
                )

        )

    [758] => Array
        (
            [0] => Array
                (
                    [0] => 16615.82
                    [1] => 2990.85
                )

            [1] => Array
                (
                    [0] => 16615.82
                    [1] => 2990.85
                )

            [2] => Array
                (
                    [0] => 16615.82
                    [1] => 2990.85
                )
        )
)

结果看起来像

Array
(
    [975] => Array
        (
            [0] => Array
                (
                    [0] => 158.7
                    [1] => 28.56
                )
        )

    [758] => Array
        (
            [0] => Array
                (
                    [0] => 49847.46
                    [1] => 8972.55
                )
        )

)

Answer 1

创建一个单独的数组，然后遍历嵌套数组并单独添加它们。如果你不能执行那个，那么你就不应该用PHP编写代码;）
