Symfony - Class, methods calling methods through pseudo-variable $this, how to do it right?

Question

PHP

Hello everyone,

there is a controller or service, etc.
This is a simple class:

public function index(Request $request, string $anyVariable){
  anyCode...
  $secondMethod = $this->secondMethod($request, $anyVariable)

  if($secondMethod){
    dosomething...
  }
}

public function secondMethod(Request $request, string $anyVariable){
  anyCode...
  return true;
}

I need to have Request in both methods, but the second method is called only through $this of the first method.

How to be here?
