在Laravelphp上合并数组

我将值 228 传递给函数 $admin_id

public function indexAll($admin_id)
    {
        $getids = User::where('ot_of', $admin_id)->pluck('id')->toArray();
        $ids = array_merge($admin_id , $getids);
        dd($ids);
}

并且$getids有这样的数据

array:2 [?
  0 => 565
  1 => 823
]

但在 $ids 中我的结果为空任何帮助都会感激不尽。结果应该是

array:2 [?
      0 => 565
      1 => 823
      2 => 228
    ]

回答

public function indexAll($admin_id)
{
    $getids = User::where('ot_of', $admin_id)->pluck('id')->toArray();
    array_push($getids,$admin_id);
    dd($getids);
}
