I want to register a bundle in the AppKernel Class in Symfony 4 according to this tutorial:
https://symfony.com/doc/3.3/bundles.html
But I do not find a folder "app", and also not the file AppKernel.php, so not the class AppKernel. Did I made a mistake by the Symfony installation or do I need to create an app folder by myself?
The structure of Symfony 4 is different with Symfony 3
if you want to enable bundle in your application you must change config/bundles.php file
something like this
// config/bundles.php
return [
// 'all' means that the bundle is enabled for any Symfony environment
Symfony\Bundle\FrameworkBundle\FrameworkBundle::class => ['all' => true],
Symfony\Bundle\SecurityBundle\SecurityBundle::class => ['all' => true],
Symfony\Bundle\TwigBundle\TwigBundle::class => ['all' => true],
.
.
.
];
