Php 三维数组和

我要这两个数组的和

第一阵列：

Array(
[abc] => Array
    (
    [yesterday] => 20
    [today] => 50
    [tomorrow] => 70
    )

[pqr] => Array
    (
    [yesterday] => 10
    [today] => 20
    [tomorrow] => 30
    )

[xyz] => Array
    (
    [yesterday] => 30
    [today] => 20
    [tomorrow] => 10
    )
)

第二阵列：

Array(
[abc] => Array
    (
    [yesterday] => 70
    [today] => 20
    [tomorrow] => 50
    )

[pqr] => Array
    (
    [yesterday] => 20
    [today] => 30
    [tomorrow] => 10
    )

[xyz] => Array
    (
    [yesterday] => 10
    [today] => 30
    [tomorrow] => 20
    )
)

两个数组的总和：

Array(
[abc] => Array
    (
    [yesterday] => 90
    [today] => 70
    [tomorrow] => 120
    )

[pqr] => Array
    (
    [yesterday] => 30
    [today] => 50
    [tomorrow] => 40
    )

[xyz] => Array
    (
    [yesterday] => 40
    [today] => 50
    [tomorrow] => 30
    )
)

我希望这能给你一个想法。我知道这个代码不是最终的结果

我希望这能给你一个想法。我知道这段代码不是最终结果。

这应该适合您：

在这里，我将使用遍历

$arr1

和

$arr2

的每个内部数组。然后我再次检查innerArray的每个值，并将它们与

array\u map（）

一起添加，然后我将返回的数组与innerArray的with键结合起来。最后，我用

$arr1

键再次组合数组

<?php

    $arr1 = [
            "abc" => [
                "yesterday" => 20,
                "today" => 50,
                "tomorrow" => 70
            ],
            "pqr" => [
                "yesterday" => 10,
                "today" => 20,
                "tomorrow" => 30
            ],
            "xyz" => [
                "yesterday" => 30,
                "today" => 20,
                "tomorrow" => 10
            ]
        ];

    $arr2 = [
            "abc" => [
                "yesterday" => 70,
                "today" => 20,
                "tomorrow" => 50
            ],
            "pqr" => [
                "yesterday" => 20,
                "today" => 30,
                "tomorrow" => 10
            ],
            "xyz" => [
                "yesterday" => 10,
                "today" => 30,
                "tomorrow" => 20
            ]
        ];  


    $result = array_combine(array_keys($arr1), array_map(function($a1, $a2){
        return array_combine(array_keys($a1), array_map(function($v1, $v2){ return $v1+$v2;}, $a1, $a2));
    }, $arr1, $arr2));


    print_r($result);

这可能不是最漂亮的解决方案，但我认为，使用此解决方案和@Rizier123的解决方案，您可以将所有内容封装在一个函数中，并使用如下函数蓝图

函数sumArrays（$array1，$array2，&output）

，而不是使用

=

使用

+=/code>

希望这有帮助

 你试过什么吗？是的，我试过for循环，但我有很多数组，所以我需要一个快捷方式。然后至少给我们看看你的尝试你试过什么吗？是的，我试过for循环，但我有很多数组，所以我需要一个快捷方式。然后至少给我们看看你的尝试hanx Rizier123，我希望我能投赞成票。thanx Rizier123，我希望我能投赞成票。
