```

Basic Usage

[](#basic-usage)

```
$eventManager = new Gamegos\Events\EventManager();
// Attach a callback to an event named 'foo'.
$eventManager->attach(
    'foo',
    function (Gamegos\Events\EventInterface $e) {
        echo sprintf('Handled "%s" event with subject "%s".', $e->getName(), $e->getSubject());
