php-symfonyHow to use a namespace in PHP Symfony?

Namespaces are used in PHP Symfony to organize classes and functions into logical groups. This helps to avoid name collisions between different classes and functions.

Example code

namespace App\Controller;

use Symfony\Component\HttpFoundation\Response;

class HelloController
{
    public function index()
    {
        return new Response('Hello World!');
    }
}

Output example

Hello World!

Code explanation

• namespace App\Controller; - This line declares the namespace of the class.
• use Symfony\Component\HttpFoundation\Response; - This line imports the Response class from the Symfony HttpFoundation component.
• class HelloController - This line declares the HelloController class.
• public function index() - This line declares the index() method of the HelloController class.
• return new Response('Hello World!'); - This line returns a new Response object with the text "Hello World!"
