Laravel 合并请求中子数组中的字段

Question

我从请求中收到此数据：

array:2 [
  0 => array:3 [
    "from" => 0
    "to" => 5
    "earned" => 0
  ]
  1 => array:3 [
    "from" => 5
    "to" => 10
    "earned" => 1
  ]
]

我想将brand_id添加到每个子数组。

我知道我可以将字段合并到请求中，例如：

$request->merge([
    'brand_id' => $brand_id,
]);

这导致：

array:3 [
  0 => array:3 [
    "from" => 0
    "to" => 5
    "earned" => 0
  ]
  1 => array:3 [
    "from" => 5
    "to" => 10
    "earned" => 1
  ]
  "brand_id" => "1"
]

我想要的结果是：

array:2 [
  0 => array:4 [
    "from" => 0
    "to" => 5
    "earned" => 0
    "brand_id" => "1"
  ]
  1 => array:4 [
    "from" => 5
    "to" => 10
    "earned" => 1
    "brand_id" => "1"
  ]
]

要是能这样就好了：

$request->merge([
    '*.brand_id' => $brand_id,
]);

注意：我已经检查过这个但如果我要使用 foreach，我将不需要进行请求合并。此外，Laravel 8.

可能还有一些新内容

试试下面的代码。您可以迭代每个元素并合并。（假设您使用的是请求对象）

$mergedArray = array_map(function($element) use ($brand_id){ 
    return array_merge($element, ['brand_id' => $brand_id]); 
}, $request->all())
