Why doesn't a private method return a result?

Question

Laravel

I have a controller with two methods

class ProfileController extends Controller
{
 public function showProfile()
  {
    self::checkUserAuth();	
  }
  
  private function checkUserAuth() 
  {
    if (Auth::check()) 
    {
    		return view('profile.index');
    }
    else
    {
      
      return redirect('/');	
    }
  }
}

}
the checkUserAuth() method does not return a result or is not called.

Answer 1

I highly recommend learning the basics of PHP.

public function showProfile()
{
    return $this->checkUserAuth();	
}

Answer 2

an error in the showProfile method... I see no point in suggesting further.
ps I advise you to read the documentation for PHP.

Answer 3

You access static methods by "::", use "->".
