composer require cboden/ratchet
Create a new WebSocket server by implementing a Chat class in your module. This class will handle message broadcasting. Register WebSocket routes in module/Application/config/module.config.php:
return [
'router' => [
'routes' => [
'websocket' => [
'type' => 'Literal',
'options' => [
'route' => '/ws',
'defaults' => [
'controller' => 'Application\Controller\Chat',
'action' => 'connect',
],
],
],
],
],
];
Next, configure the controller to handle real-time data:
namespace Application\Controller;
use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;
class Chat implements MessageComponentInterface
{
public function onOpen(ConnectionInterface $conn) {
// New connection established
}
public function onMessage(ConnectionInterface $from, $msg) {
// Broadcast message to all connected clients
}
public function onClose(ConnectionInterface $conn) {
// Connection closed
}
public function onError(ConnectionInterface $conn, \Exception $e) {
// Handle error
}
}
By setting up these components, users can send and receive messages in real time, enabling a fully functional communication tool built with Zend Framework.
