Flexible fetching Laravel?

Question

Laravel

Hello.
I want to implement Laravel fetching by GET request parameters. I accept values ​​through $request->input(), how can I correctly substitute this array in ->where(), to select by key=value from the get request?
For example: /news?category_id=2¤cy=5
->where('category_id', 5)->where('currency', 5) etc.
