PHP中的组合字符串和数值两个多维数组的求和

Question

我下面有两个包含字符串和数字的数组，

我只想保留一个字符串标题，并将每个键值的数值与另一个数组求和。

我已经尝试了许多在线可用的解决方案，但未找到所需的解决方案。

$array1 = 
Array
(
    [0] => Array
        (
            [0] => Out Of Warranty
            [1] => Total Orders
            [2] => Total Qty
            [3] => Canceled Orders
        )

    [1] => Array
        (
            [0] => Today<br/>(04-26-2020)
            [1] => 1
            [2] => 1
            [3] => 0
        )

    [2] => Array
        (
            [0] => Yesterday<br/>(04-25-2020)
            [1] => 0
            [2] => 0
            [3] => 0
        )

    [3] => Array
        (
            [0] => This Week<br/>(04-20-2020 - 04-26-2020)
            [1] => 22
            [2] => 39
            [3] => 0
        )

    [4] => Array
        (
            [0] => Last Week<br/>(04-13-2020 - 04-19-2020)
            [1] => 7
            [2] => 7
            [3] => 0
        )

    [5] => Array
        (
            [0] => This Month<br/>(04-01-2020 - 04-26-2020)
            [1] => 29
            [2] => 46
            [3] => 0
        )

    [6] => Array
        (
            [0] => This Year<br/>(01-01-2020 - 04-26-2020)
            [1] => 30
            [2] => 47
            [3] => 0
        )

)

$array2 = 
Array
(
    [0] => Array
        (
            [0] => Out Of Warranty
            [1] => Total Orders
            [2] => Total Qty
            [3] => Canceled Orders
        )

    [1] => Array
        (
            [0] => Today<br/>(04-24-2020)
            [1] => 10
            [2] => 10
            [3] => 0
        )

    [2] => Array
        (
            [0] => Yesterday<br/>(04-23-2020)
            [1] => 7
            [2] => 7
            [3] => 0
        )

    [3] => Array
        (
            [0] => This Week<br/>(04-20-2020 - 04-24-2020)
            [1] => 51
            [2] => 51
            [3] => 0
        )

    [4] => Array
        (
            [0] => Last Week<br/>(04-13-2020 - 04-19-2020)
            [1] => 31
            [2] => 31
            [3] => 0
        )

    [5] => Array
        (
            [0] => This Month<br/>(04-01-2020 - 04-24-2020)
            [1] => 93
            [2] => 93
            [3] => 0
        )

    [6] => Array
        (
            [0] => This Year<br/>(01-01-2020 - 04-24-2020)
            [1] => 1281
            [2] => 1281
            [3] => 1
        )

)

作为字符串的预期输出应仅使用一次，并且数字应相互添加。

例如，输出应为6索引，即array1和array2的6索引之和-

[6] => Array
            (
                [0] => This Year<br/>(01-01-2020 - 04-26-2020)
                [1] => 1311
                [2] => 1328
                [3] => 1
            )

如果您的数组总是按相同的顺序排序：

$newItems = [];
foreach ($array1 as $key => $item) {
    $newItems[] = [
        $item[0],
        $item[1] + $array2[$key][1],
        $item[2] + $array2[$key][1],
        $item[3] + $array2[$key][1],
    ];
}

如果键以不同的顺序排列在数组中：

$newItems = [];
foreach ($array1 as $item) {
    $name = $item[0]
    $newItems[$name] = $item;
}
foreach ($array2 as $item) {
    $name = $item[0]
    $newItems[$name][1] += $item[1];
    $newItems[$name][2] += $item[2];
    $newItems[$name][3] += $item[3];
}
// apply array_values to get 0-indexed array
$newItems = array_values($newItems);
