Item Count

How do I get how many pots were left when the player died?

PHP:

    public function getPotionCount(Player $sender){
        $name = $sender->getName();
        $number = 0;
        $inventory = $sender->getInventory();
        foreach($inventory->getContents() as $item){
            if ($item instanceof \pocketmine\item\Potion or $item instanceof \pocketmine\item\SplashPotion) {
                $number = $number + $item->getCount();
            }
        }

        return $number; 
    }

//returns the number of potions left
$this->getPotionCount($sender)
