Code Example

Let's create Event Order was placed.

class OrderWasPlaced
{
    private string $orderId;
    private string $productName;

    public function __construct(string $orderId, string $productName)
    {
        $this->orderId = $orderId;
        $this->productName = $productName;
    }

    public function getOrderId(): string
    {
        return $this->orderId;
    }

    public function getProductName(): string
    {
        return $this->productName;
    }
}

And Event Handler that will be listening to the OrderWasPlaced.

class NotificationService
{
    #[EventHandler]
    public function notifyAboutNewOrder(OrderWasPlaced $event) : void
    {
        echo $event->getProductName() . "\n";
    }
}

Running The Example

$eventBus->publish(new OrderWasPlaced(1, "Milk"));
