and some other code:

$pics = '';
        $logos = "http://www.supercarworld.com/images/logos/";
        $gif = ".gif";


        for ($x = 0; $x < count($makes); $x++) { 



                $pics = array($logos.$makes[$x].$gif);






            print_r($pics[$x]);












        $car = new Car();
        $car->setName('http://www.supercarworld.com/images/fullpics/595.jpg');

        // em entity manager
        $em = $this->getDoctrine()->getManager();
        $em->persist($car);
        $em->flush();


        $car = $this->getDoctrine()
        ->getRepository('GrupaProjektBundle:Car')
        ->findOneBy(array('id' => $car->getId(), 'name' => $car->getName()));
        return $this->render('GrupaProjektBundle:Sc:supercars.html.twig', array('car' => $car,
                                                                                'pics' => $pics[$x],
                                                                                ));
        } 

and when I want to get [$x] the behaviour is weird it displays only zero element i.e 9FF but when I get [0] or [1] from $makes it works Why? I want to make it to iterate am I missing some incrementation?
