Php 如何将两个数组组合为键和值？

在一个数组中有键，在另一个数组中有值。我希望以如下所示的方式将这两个数组组合为array1的所有键和array2的所有值。如何在PHP中实现这一点

这是两个数组

    Array
    (
        [0] => url
        [1] => downloadName
        [2] => downloadType
        [3] => downloadSize
        [4] => url
        [5] => downloadName
        [6] => downloadType
        [7] => downloadSize
    )
    Array
    (
        [0] => https://www.clearcube.com/support/controller/downloads.php?id=450
        [1] => F6151 Media Converter System with 100 base TX to 100 base FX.pdf
        [2] => Manual
        [3] => 0.39
        [4] => https://www.clearcube.com/support/controller/downloads.php?id=582
        [5] => G0400147 Rev B.xlsx
        [6] => Manual
        [7] => 0.37
    )

我需要这种格式。

Array
(
    [url] => Array(
        [0] => https://www.clearcube.com/support/controller/downloads.php?id=450
        [1] => https://www.clearcube.com/support/controller/downloads.php?id=582
    )

    [downloadName] => Array(
        [0] => F6151 Media Converter System with 100 base TX to 100 base FX.pdf
        [1] => G0400147 Rev B.xlsx
    )

    [downloadType] => Array(
        [0] => Manual
        [1] => Manual
    )

    [downloadSize] => Array(
        [0] => 0.39
        [1] => 0.37
    )
)

一个简单的方法是

$result = [];
foreach ($array1 as $key1 => $value1) {
    $result[$value1][] = $array2[$key1];
}

独立于索引执行验证

if (count($array1) == count($array2)) {
    $result = [];
    $i = 0;
    foreach ($array1 as $value1) {
        $j=0;
        foreach ($array2 as $value2) {
            if ($j == $i) {
                $result[$value1][] = $value2;
                break;
            }
            $j++;
        }
        $i++;
    }
    var_dump($result);
}

假设key array是$arr1，data array是$arr2，那么您可以运行以下循环并通过以下方式创建新数组

$new_arr = []
foreach($arr1 as $key=>$arr){
    $new_arr[$arr][] = $arr2[$key];
}
//final array is $new_arr

在你的帮助下，你可以很容易地把它组合起来

$keys = ['url','downloadName','downloadType','downloadSize','url','downloadName','downloadType','downloadSize'];
$values = [ 'https://www.clearcube.com/support/controller/downloads.php?id=450', 'F6151 Media Converter System with 100 base TX to 100 base FX.pdf', 'Manual', 0.39, 'https://www.clearcube.com/support/controller/downloads.php?id=582', 'G0400147 Rev B.xlsx', 'Manual', 0.37 ];

$result = [];
array_walk($keys, function ($val, $key) use (&$result, $values) { $result[$val][] = $values[$key]; });

print_r($result);

工作

输出：

Array
(
    [url] => Array
        (
            [0] => https://www.clearcube.com/support/controller/downloads.php?id=450
            [1] => https://www.clearcube.com/support/controller/downloads.php?id=582
        )

    [downloadName] => Array
        (
            [0] => F6151 Media Converter System with 100 base TX to 100 base FX.pdf
            [1] => G0400147 Rev B.xlsx
        )

    [downloadType] => Array
        (
            [0] => Manual
            [1] => Manual
        )

    [downloadSize] => Array
        (
            [0] => 0.39
            [1] => 0.37
        )
)

您可以使用基于索引的方法，首先检查数组的长度是否相同

循环数组1中的键，并为该键添加数组2中的值

$result = [];

if (count($array1) === count($array2)) {
    for ($i = 0; $i < count($array1); $i++) {
        $result[$array1[$i]][] = $array2[$i];
    }
}

print_r($result);

欢迎来到堆栈溢出。请分享您迄今为止所做的尝试，以及您在这样做时遇到的错误。Stack overflow不是一个发布需求并接收运行程序/代码的平台。也许可以帮助你更新你的问题，这样人们就能真正帮助你。我认为你的第一个问题是你的数组的结构，它真的很奇怪
