pass repository to class from Command Symfony - php

Question

I have a code in Symfony 3.2, where I am trying to pass repository from Commmand class to my custom class, where I am running the websockets
<?php
namespace MyBundle\Command;
use MyBundle\Server\Notification;
use Ratchet\Http\HttpServer;
use Ratchet\Server\IoServer;
use Ratchet\WebSocket\WsServer;
use Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
class ServerCommand extends ContainerAwareCommand
{
/**
* Configure a new Command Line
*/
protected function configure()
{
$this->setName('Project:notification:server')
->setDescription('Start the notification server.');
}
protected function execute(InputInterface $input, OutputInterface $output)
{
$em = $this->getApplication()->getKernel()->getContainer()->get('My.repository.car');‏
$server = IoServer::factory(new HttpServer(
new WsServer(
new Notification($this->getContainer(),$em)
)
), 8080);
$server->run();
}
}
for All my db queries I am using repositories and there is no Entity. I have done this before, and it was working fine.
But now when I run command from terminal I am getting this error
Parse error: parse error in
/Applications/XAMPP/xamppfiles/htdocs/lavtaxi/src/MyBundle/Command/ServerCommand.php
on line 28
on line 28 there is
"$server = IoServer::factory(new HttpServer( " part
this is my services.yml
services:
My.repository.car:
class: MyBundle\Repository\CarRepository
arguments: ["#doctrine.orm.entity_manager"]
and this is Notification.php where I am trying to get data and send via sockets
<?php
namespace MyBundle\Server;
use Doctrine\ORM\EntityManager;
use Ratchet\ConnectionInterface;
use Ratchet\MessageComponentInterface;
use Symfony\Component\DependencyInjection\ContainerInterface;
class Notification implements MessageComponentInterface
{
protected $connections = array();
private $users = array();
protected $container;
private $drivers = array();
private $repository = null;
public function __construct(ContainerInterface $container, $em)
{
$this->repository = $em;
$this->container = $container;
$this->users = [];
$this->drivers = [];
}
/**
* A new websocket connection
*
* #param ConnectionInterface $conn
*/
public function onOpen(ConnectionInterface $conn)
{
$this->connections[] = $conn;
$this->users[$conn->resourceId] = $conn;
$this->drivers = $this->repository->getCarsData();
$conn->send('..:: Hello from the Notification Center ::..');
$conn->send(json_encode($this->drivers));
echo "New connection \n";
}
}
Error is disappears when I remove the repository calling part above, so I know that problem is not on IoServer
