php-symfonyHow to use the messenger component in PHP Symfony?

The Messenger component in PHP Symfony is a powerful tool for sending and receiving messages between applications. It allows you to send messages asynchronously, which can be useful for tasks such as sending emails or performing background tasks.

Example code

use Symfony\Component\Messenger\MessageBusInterface;

class MyService
{
    private $bus;

    public function __construct(MessageBusInterface $bus)
    {
        $this->bus = $bus;
    }

    public function doSomething()
    {
        $this->bus->dispatch(new MyMessage());
    }
}
