$array = [
    ['name' => 'Jone', 'age' => 23],
    ['name' => 'Mike', 'age' => 18],

    ['developer' => ['name' => 'Mike', 'age' => 18]],
    ['developer' => ['name' => 'Jordan', 'age' => 31]],
    ['developer' => ['name' => 'Rickey', 'age' => 28]],

array:5 [▼
  0 => 23
  1 => 18
  2 => 31
  3 => 28
  4 => 21
]

Example 3: User Arr::pluck() With List Key

In this last example you can see that I have passed the third argument in Arr::pluck() helper function, which will return list.name as key and age as value.

use Illuminate\Support\Arr;

$array = [
    ['developer' => ['name' => 'Jone', 'age' => 23]],
    ['developer' => ['name' => 'Mike', 'age' => 18]],
    ['developer' => ['name' => 'Jordan', 'age' => 31]],
    ['developer' => ['name' => 'Rickey', 'age' => 28]],
    ['developer' => ['name' => 'Russle', 'age' => 21]],
];

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

// OUTPUT

array:5 [▼
    "Jone" => 23
    "Mike" => 18
    "Jordan" => 31
    "Rickey" => 28
    "Russle" => 21
]
