Laravel - 将多个数组合并为一个对象

Let's say I have this PHP code using Laravel 5.6:

$action = [
    [
        "name" => "action",
        "value" => "DepositMoney"
    ],
    [
        "name" => "coins",
        "type" => "number",
        "value" => "534"
    ]
];

return collect($action)->map(function($item, $key) {
    return [
        $item['name'] => $item['value']
    ];
});

which produces:

[
  {
    "action": "DepositMoney"
  },
  {
    "coins": "534"
  }
]

How do I make it so I can merge those together and produce this instead (using something from here: https://laravel.com/docs/5.6/eloquent-collections#available-methods):

[
    "action" => "DepositMoney",
    "coins" => "534"
]

Thanks. This is for form_params on Guzzle.

    You need the reduce() function, to create a single value from multiple elements of an array. Documentation is here: https://laravel.com/docs/5.6/collections#method-reduce

    I would suggesting trying this (I didn't test it, but you get the idea, and should be able to understand how to use reduce from this example):

    return collect($action)->map(function($item, $key) {
        return [
            $item['name'] => $item['value']
        ];
    })->reduce(function ($carry, $item) {
        foreach ($item as $k => $v) {
            $carry[$k] = $v;
        }
        return $carry;
    });
