Is Twig, the default template engine in Symfony, widely used in production environments, or are there alternative template engines that are preferred in PHP development?

Twig is widely used in production environments for Symfony projects due to its simplicity, security features, and integration with Symfony components. While there are alternative template engines available for PHP development, Twig remains a popular choice among Symfony developers for its ease of use and robust functionality.

// Example of using Twig in Symfony controller
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;

class MyController extends AbstractController
{
    /**
     * @Route("/my-route", name="my_route")
     */
    public function myAction(): Response
    {
        return $this->render('my_template.html.twig', [
            'variable' => 'value',
        ]);
    }
}
