Method 1

Here is how you can achieve it

$created_at = Post::select(DB::raw('MONTH(created_at) as month'))->get();

If you want to get only simple array which is mostly we use in line graphs

$created_at = User::select(DB::raw('MONTH(created_at) as month'))->get();
$array  = [];
foreach($created_at as $month) {
  $array[] = $month->month;
}
dd($array);
