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"));
