Error: Cannot use object of type Symfony\Component\HttpFoundation\Request as array

Question

When I showed it in a browser when upgrading to symfony3, I had a title error (line 25).
I had questions on similar mistakes in StackOverflow, but I think it's a different trend.
I want to know how it can be improved.

Answer 1

The error was resolved when I fixed it as follows.

    public function preControllerExecute(FilterControllerEvent $event)
    {
        if (HttpKernelInterface::MASTER_REQUEST === $event->getRequestType()) {
            $request = $event->getRequest();
            $_controller = $event->getController();

        if (isset($_controller[0])) {
            $controller = $_controller[0];
                if (method_exists($controller, 'preExecute')) {
                    $controller->preExecute($request);
                }
        }
        }
    }
