Add IF ELSE condition in Laravel Eloquent

$type = $request->input('email_or_phone');

$user = UserVerify::where('user_id', $request->input('user_id'))
                    ->where(function($query) use ($type, $request) {
                        if ($type == 1) {
                            return $query->where('email', $request->input('email'));
                        }
                        if ($type == 2) {
                            return $query->where('mobile_no', $request->input('mobile_no'));
                        }
                    })
                    ->where('email_or_phone', $request->input('email_or_phone'))
                    ->where('pin_code', $request->input('pin_code'))
