save field values in a laravel variable

I hope you can help me clarify a little better what I have to do with laravel.

I need to take 3 values that I will write in 3 fields and send them to some temporary variables in php, I do not need to record them in the database or anything, I only need them to be saved in these 3 fields.

Inside the config folder, I have a file called variables, with the following.

<?php



return [


    'boolean' => [
        '0' => 'No',
        '1' => 'Si',
    ],

     'SINO' => [
        'NO' => 'NO',
        'SI' => 'SI',
    ],


    'estado' => [
        'NORMAL' => 'NORMAL',
        'NO NORMAL' => 'NO NORMAL',
    ],

];

and I use these static variables in this way:

{!! Form::mySelect('estadocita', 'Estado cita: ', config('variables.boolean')) !!}

What I need is to create other variables:

'ejemplo' => [
            '0' => 'No',
            '1' => 'Si',
        ],

But that I can store data in those variables from a form.

Can someone give me a guide with an example please? I know that "messing around" I can do it, but I have not found an example that fits what I need to be able to mold it and apply it.

I appreciate your attention.

EDIT

So far I did this.

I have these fields in my view

                    <
                  {!! Form::open([
                    'action' => ['CategoriesController@store'],
                    'files' => true
                        ])
                    !!}
                  <input type="" name="nombre" class="logo-lg">
                  <input type="" name="nombre2" class="logo-lg">
                  <input type="" name="nombre3" class="logo-lg">
                  <button type="submit" class="btn btn-info" style="width:100px;">Guardar</button>

And I have this function:

public function store(Request $request)
{
    $nombre = $request->input("nombre");
    $nombre2 = $request->input("nombre2");
    $nombre3 = $request->input("nombre3");

    echo $nombre;
    echo $nombre2;
    echo $nombre3;

(And if you print me the values I'm sending)

But, I just need to be able to save those values in the variable file that I have saved in my config folder.

To be able to call that data from other windows, can Alguiem help me?
