use Phauthentic\EventStore\Event;
use Phauthentic\EventStore\InMemoryEventStore;
use Phauthentic\EventStore\ReplyFromPositionQuery;

$eventStore = new InMemoryEventStore();

$event = new Event(
    aggregateId: 'order-123',
    aggregateVersion: 1,
    event: 'OrderCreated',
    payload: ['amount' => 99.99],
    createdAt: new \DateTimeImmutable()
);

$eventStore->storeEvent($event);

foreach ($eventStore->replyFromPosition(new ReplyFromPositionQuery('order-123', 1)) as $storedEvent) {
    // Process event...
