Template engine

Twig, The flexible, fast, and secure template engine for PHP

The template engine of choice for this project is Twig and can be used to render anything HTML related. If you prefer to use another template engine, just add in to the container and re move the twig entry. You should be good to go.s

Create a template​

Start off with creating a new file in the templates directory

templates/users.html.twig
<h1>Users</h1>
<ul>
    {% for user in users %}
        <li>{{ user.username|e }}</li>
    {% endfor %}
</ul>

Render the template​

Then render your template in for example a RequestHandler, by injecting the Twig environment:

UserOverviewRequestHandler.php
class UserOverviewRequestHandler
{
    public function __construct(
        private readonly Environment $twig,
    ) {
    }

    public function handle(
        ServerRequestInterface $request,
        ResponseInterface $response): ResponseInterface
    {
        $template = $this->twig->load('users.html.twig');
        $response->getBody()->write($template->render(/*...*/));

        return $response;
    }
}
