This library allows you to watch events and react to them.

Usage instructions and more information can be found [in our Wiki](https://github.com/FlameCore/EventObserver/wiki).

Getting Started
---------------

[](#getting-started)

Create a new Responder object which holds the event listeners:

```
$responder = new Responder();
$responder->setListener('action.event', function (array $data, $event) {
    print_r($data);
});
```

Create a new Observer object and give it some actions to react to:

```
$observer = new Observer();
$observer->addResponder('action', $responder);
```

Notify the Observer of events (optionally with data):

```
$observer->notify('action.event');
$observer->notify('action.event', ['some_data' => 123.4]);
```

Installation
------------
