When I start working on Laravel 5.2 at that time I get this problem “class’ input not found”. I got this problem at the time when I copied my old controller code from the Larva 5.1 version, but I could also use the input input for the request, but I want to use the input. But the final solution was found. You just have to use aliases on your controller.
use IlluminateSupportFacadesInput as Input
