Lack of class casting leads to inspection message. How to avoid (in code)?

Hi @ all,

my code is calling a method, which is hidden by downcasting. This works well with PHP, would not work in strong casting languages like C++, and produces a message by the PhpStorm Inspector. Since there is no explicit object casting in PHP, what is the best practice for this kind of code? Just using /** @noinspection PhpUndefinedMethodInspection */ ?  Or did I miss any kind of casting?

A (very simple and untested) example code is here:

class Car {
   public function speedUp() {;}
}

class Hybrid extends Car {
   public function startFuelMode() {;}
}

function moveCar(Car $car) { //downcast to have a general method
   if ($car instanceof Hybrid) {
      $car->startFuelMode(); // PhpStorm Inspector -> Method 'startFuelMode' not found in class
   }
   $car->speedUp();
}


$myHybrid = new Hybrid();
moveCar($myHybrid); // $myHybrid is downcasted to Car

One solution in C++ (with PHP syntax) would be:

      //$car->startFuelMode(); // PhpStorm Inspector -> Method 'startFuelMode' not found in class
      ((Car)$car)->startFuelMode();


Any comments are appreciated.


I use PhpStorm 6.0.3
