in Devristo\Phpws\Protocol\WebSocketTransport,
$data parameter is not needed in close event ?

        $socket->on("close", function($data) use ($that){
            $that->emit("close", func_get_args());
        });

Hey, were you able to fix this issue? Where is this code from:

$socket->on("close", function($data) use ($that){
    $that->emit("close", func_get_args());
});
