错误：不能使用 Symfony\Component\HttpFoundation\Request 类型的对象作为数组

Question

当我在升级到 symfony3 时在浏览器中显示它时，出现标题错误（第 25 行）。
我对 StackOverflow 中的类似错误有疑问，但我认为这是一个不同的趋势。
我想知道如何改进它。

当我按如下方式修复时，错误已解决。

    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);
                }
        }
        }
    }
