3. How to use the Symfony6 framework?

Symfony6 framework is the latest version of Symfony framework. Here are the steps to use the Symfony6 framework:

1. Install the Symfony6 Framework

First, you need to install the Symfony6 framework on your machine. The Symfony6 framework can be installed using the composer tool as follows:

$ composer create-project symfony/skeleton my-project

This will create a Symfony6 framework application in the my-project directory.

2. Create a Controller

The controller is the main component that interacts with the user. It is responsible for processing HTTP requests and generating responses. You can create a controller class like this:

// src/Controller/HelloController.php
namespace AppController;

use SymfonyComponentHttpFoundationResponse;

class HelloController
{

public function index(): Response
{
    return new Response('Hello Symfony!');
}

}

In the above code, the "HelloController" class handles the URL "/hello" and returns the response "Hello Symfony!"

3. Configuring Routing

Routing is the rule that determines how applications based on HTTP requests are executed. To configure routing, create a routes file as follows:

// config/routes.yaml
hello:

path: /hello
controller: AppControllerHelloController::index

In the above code, the "hello" route matches "/hello" URL, and call the "index" method of "HelloController".

4. Run the application

Finally, you need to run the Symfony6 application in the terminal. The server can be started using the following command:

$ symfony server:start

This will start the Symfony6 application and listen for HTTP requests. Now, when you visit "http://127.0.0.1:8000/hello", you will see "HelloSymfony!"

IV. Summary
