【问题描述】：

我有这种情况：

$variation = [

    "sku" =>  [
        0 => "dSADad",
        1 => "ASDAF",
        2 => "ASFAS",
        // ...
    ],
    "Price" => [
        0 => "1",
        1 => "1",
        2 => "1",
        // ...
    ],
    "Quantity" =>  [
        0 => "123",
        1 => "123",
        2 => "123434",
        // ...
    ],
    "attributes" => [

        "Color" => [
            0 => "5",
            1 => "4",
            2 => "4",
            // ...
        ],
        "Size" =>  [
            0 => "3",
            1 => "3",
            2 => "2",
            // ...
        ],
        "Material" =>  [
            0 => "7",
            1 => "7",
            2 => "8",
            // ...
        ],
    ],
];

我想将其转换为按单独的变体分组，如下例所示：我尝试了几种选择但没有结果。我也试过在提交前用JS给输入添加索引，但还是不行。剩下的唯一选择是将其转换为 php..

$variations = [

    0 => [

        "Sku" =>  [
            0 => "dSADad",
        ],
        "Price" => [
            0 => "1",
        ],
        "Quantity" =>  [
            0 => "123",
        ],
        "attributes" => [

            "Color" => [
                0 => "5",
            ],
            "Size" =>  [
                0 => "3",
            ],
            "Material" =>  [
                0 => "7",
            ],
        ],
    ],
    1 => [

        "Sku" =>  [
            1 => "ASDAF",
        ],
        "Price" => [
            1 => "1",
        ],
        "Quantity" =>  [
            1 => "123",
        ],
        "attributes" => [

            "Color" => [
                1 => "4",
            ],
            "Size" =>  [
                1 => "3",
            ],
            "Material" =>  [
                1 => "7",
            ],
            // ....
        ],
    ]
// ...
];

【解决方案1】：

我设法制作了这段代码：

function extractVariation($variations, $key)
{
    $variation = [];
    foreach ($variations as $property => $values) {
        if (isset($values[$key])) {
            $variation[$property] = $values[$key];
        } else {
            $variation[$property] = extractVariation($values, $key);
        }
    }
    return $variation;
}

$newVariations = [];

foreach ($variations['sku'] as $key => $sku) {
    $newVariations[] = extractVariation($variations, $key);
}

var_export($newVariations);

在此处查看工作示例：https://3v4l.org/l4gJQ

请注意，我将您的$variation 数组重命名为$variations。

该函数是递归的，允许它进入属性数组。

输出是：

array (
  0 => 
  array (
    'sku' => 'dSADad',
    'Price' => '1',
    'Quantity' => '123',
    'attributes' => 
    array (
      'Color' => '5',
      'Size' => '3',
      'Material' => '7',
    ),
  ),
  1 => 
  array (
    'sku' => 'ASDAF',
    'Price' => '1',
    'Quantity' => '123',
    'attributes' => 
    array (
      'Color' => '4',
      'Size' => '3',
      'Material' => '7',
    ),
  ),
  2 => 
  array (
    'sku' => 'ASFAS',
    'Price' => '1',
    'Quantity' => '123434',
    'attributes' => 
    array (
      'Color' => '4',
      'Size' => '2',
      'Material' => '8',
    ),
  ),
)

展示你的尝试总是更好的，即使它不能完全奏效。这样，这里的人就可以看出您不是简单地要求他们为您编写代码，而是您确实有问题。
