fetch record that is equal to 1 or 0 laravel eloqouent

Question

I'm using this one

$notification = notification::where('department', '=', 1)->get();

to fetch all records that has 'department' of 1 in my database (it works)

Now, I want to fetch also all records that neither has 'department' of 1 or 0, any ideas, help?

Answer 1

如何使用whereIn或whereNotIn子句？

$notification = notification::whereIn('department', [1, 2])->get();
