我如何格式化以下 laravel collection

Question

提前致谢！我在 Laravel.

中有以下 collection

$data = collect([
    [
        'id' => 1,
        'filter' => 'brand',
        'value' => 'apple'
    ],
    [
        'id' => 2,
        'filter' => 'color',
        'value' => 'red'
    ],
    [
        'id' => 3,
        'filter' => 'color',
        'value' => 'blue'
    ],
    [
        'id' => 3,
        'filter' => 'storage',
        'value' => '8GB'
    ]
]);

我需要这样的：


[
    "brand" => ["apple"],
    "color" => ["red", "blue"],
    "storage" => ["8GB"]
]

如何像上面那样格式化？

我找到了解决方案。

$grouped = $collection->mapToGroups(function ($item, $key) {
    return [$item['filter'] => $item['value']];
});

$grouped->toArray();
