Removing Single Item From Players Hand

I'm trying to remove a single item from the players hand when the player taps on a block. Can't get it to work though.

PHP:

public function blockTouchEvent($data, $event){
        $item = $data["item"]->getID();
        $player = $data["player"];
        if($player->hasItem($item, false)){
            var_dump($player->removeItem($item, false, 1, true));
            return false;
        }else{
            return true;
        }
}


It returns "bool(false)", so it's getting to the 5th line. Any suggestions?

Still can't figure this out. Does anyone know how to do this?
