Q
Flex
Symfony Flex is a Composer plugin already installed with Symfony.
composer create-project symfony/skeleton flex
cd flex/
Recipe
# Twig is not the name of a Composer package (it is a Flex alias).
# Flex resolves that alias for Composer.
# Flex installs a recipe for symfony/twig-bundle.
# A recipe is a way for a library to automatically configure itself.
composer require twig
composer require profiler
composer require api
composer remove api
composer remove vendor/package
symfony server:start
http://localhost:8000 # Welcome to Symfony
Twig
Twig is a fast and secure template engine for PHP.
/**
* DefaultController
*
* src/Controller/DefaultController
*
* Starting from Symfony 5.0 support for PHP templates was removed.
* Only Twig templates can be used.
*
* http://localhost:8000/hello # Hello WORLD
* http://localhost:8000/hello/Symfony # Hello SYMFONY
*
*/
namespace App\Controller;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
class DefaultController extends AbstractController
{
/**
* @Route("/hello/{name}")
*/
public function hello($name='World')
{
return $this->render('default/index.html.twig', [
'name' => $name,
]);
}
}
Templates
Twig compiles templates down to plain optimized PHP code.
<!-- templates/default/index.html.twig -->
{% include 'header.html.twig' %}
<b>Hello name|upper</b>
