Client Example

The Client is not as interesting as the server and is mainly used to test the server

<?php        require_once("websocket.client.php");        $input = "Hello World!";        $msg = WebSocketMessage::create($input);        $client = new WebSocket("ws://127.0.0.1:12345/echo/");        $client->sendMessage($msg);        // Wait for an incoming message        $msg = $client->readMessage();        $client->close();        echo $msg->getData(); // Prints "Hello World!" when using the demo.php server
