I’m trying to learn Laravel.

I pushed my project to GitHub so you can check all the code you need:
https://github.com/wolfpain/fibobet/tree/master

I’m working on a controller function but I don’t understand how to call that method in another method of the same controller.

Here are my two methods:

/**
 * Count last extraction
 */
public function count($column)
{
    $lastNumber = Number::all()->orderBy('created_at', 'DESC')->first();
    $lastColumn = Number::find()->where('column', $column)->take(1);
    $count = $lastNumber - $lastColumn;
    return $count;
}

/**
 * Display a listing of the resource.
 */
public function index()
{
    $count = count(1);
    //
    $numbers =  Number::all();

    return view('index', ['numbers' => $numbers, 'count' => $count]);
}

I need to call function count() inside the index() function and send the $count variable to the index view.

I try to call the function like:

 count(1);

but nothing happened. I try:

NumberCOntroller::class->count(1); 

too but the result is the same.

How can I call the count() function?

If I add:

return view('index', ['numbers' => $numbers, 'count' => $count]);

At the view I get this error:

Undefined variable $count

This is the code of the view show the $count variable:
