如何将转换后的数组提取到集合

Question

我将此数组转换为集合

array:1 [
"params" => array:3 [
"total_amount" => "2.37"
"user_id" => 3
"used_currency" => "YER"
]
]

$items = collect(request()->all());

当将total_amount值转换为集合时，如何采摘它。

dd($items->get('params.total_amount'));

Answer 1

只需访问集合中的数组键

dd($items->get('params')['total_amount']);

希望这会有所帮助

Answer 2

您仅将外部数组转换为集合，而不是内部数组。

要将所有数组转换为集合，请在json_decode之后使用json_encode。

$abc =  [
    "params" => [
        "total_amount" => "2.37",
        "user_id" => 3,
        "used_currency" => "YER"
    ]
];
$collect = collect(json_decode(json_encode($abc)));

return dd($collect->pluck('total_amount'));

这样，如果您的数据如下所示，则可以使用所有收集方法，例如所有“ total_amount”之和

$abc =  [
    "params1" => [
        "total_amount" => "2.37",
        "user_id" => 3,
        "used_currency" => "YER"
    ],
    "params2" => [
        "total_amount" => "2.37",
        "user_id" => 3,
        "used_currency" => "YER"
    ],
];
$collect = collect(json_decode(json_encode($abc)));
return dd($collect->pluck('total_amount')->sum());
