Laravel - Requests - Retrieving A Portion Of The Input Data

If you need to retrieve a subset of the input data, you may use the only and except methods. Both of these methods accept a single array or a dynamic list of arguments:

    $input = $request->only(['username', 'password']);
    $input = $request->only('username', 'password');
    $input = $request->except(['credit_card']);
    $input = $request->except('credit_card');
The only method returns all of the key / value pairs that you request; however, it will not return key / value pairs that are not present on the request.
