Install ElephantIO/elephant.io lib via composer:

composer require elephantio/elephant.io

Yii2 Elephant IO implementation. This is a really dirt simple extension which just wraps the Elephant IO module into a Yii2 Component. We updated source source code for socket.io version 4 or larger. You can configure it in your application configuration like so:

'elephantio' => [
      'class' => 'app\classes\ElephantIo',
      'host' => 'http://127.0.0.1:3021'
]

Adding it to your components array.

\Yii::$app->elephantio->emit('setuser',  ['foo' => 'bar']);
\Yii::$app->elephantio->close();

I hope it will be helpful for you! Thanks
