php - 如何将对象数组转换为键值对数组？

Question

我从 Laravel 查询生成器获得了一个对象数组:

[
 {
   "name": "John",
   "code": "006"
 },
 {
   "name": "James"
   "code": "007"
 },
 {
   "name": "Jone"
   "code": "008"
 }
]

我想把它变成这样:

[
  "John"  => "006",
  "James" => "007",
  "Jone"  => "008"
]

Answer 1

如果你有一个数组:

\Illuminate\Support\Arr::pluck($array, 'code', 'name');
array_pluck($array, 'code', 'name');

如果您有收藏:

$collection->pluck('code', 'name');

您还可以从查询中提取:

$query->pluck('code', 'name'); // instead of the `get` call
