如何从laravel集合中改变数组结构？

$collection = collect([
    ['name' => 'John', 'age' => 25],
    ['name' => 'Jane', 'age' => 30],
]);

$newCollection = $collection->map(function ($item) {
    return [
        'label' => $item['name'],
        'value' => $item['age'],
    ];
});

$collection = collect([
    ['name' => 'John', 'age' => 25],
    ['name' => 'Jane', 'age' => 30],
]);

$newCollection = $collection->mapWithKeys(function ($item) {
    return [
        $item['name'] => $item['age'],
    ];
});
