Laravel 8 Arr::pluck() {#collection-method}

2021-07-19 10:18 更新

Arr::pluck 函数从数组中检索给定键的所有值：

use Illuminate\Support\Arr;

$array = [
    ['developer' => ['id' => 1, 'name' => 'Taylor']],
    ['developer' => ['id' => 2, 'name' => 'Abigail']],
];

$names = Arr::pluck($array, 'developer.name');

// ['Taylor', 'Abigail']

你也可以指定结果的键：

use Illuminate\Support\Arr;

$names = Arr::pluck($array, 'developer.name', 'developer.id');

// [1 => 'Taylor', 2 => 'Abigail']
