How to render a twig template in a Symfony controller?

To render a Twig template in a Symfony controller, you can use the render() method of the Symfony\Bundle\FrameworkBundle\Controller\AbstractController class. Here's an example:

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundationResponse;

class MyController extends AbstractController
{
    public function myAction(): Response
    {
        $data = [
            'name' => 'John',
            'age' => 30,
        ];

        return $this->render('my_template.html.twig', $data);
    }
}

In this example, the myAction() method is defined in a controller called MyController. The method returns the result of the render() method, which takes two arguments:

• The name of the Twig template to render (my_template.html.twig in this example).
• An associative array of data to be passed to the template ($data in this example).

The render() method returns an instance of the Symfony\Component\HttpFoundationResponse class, which represents the HTTP response that will be sent back to the client.

Note that the AbstractController class provides some convenient methods for working with templates and other common tasks in Symfony controllers. If you're not using AbstractController, you can still use the render() method by injecting the Symfony\Component\Templating\EngineInterface service into your controller and calling its render() method.
