How does WebSocket API impact performance or memory usage?

The WebSocket API significantly enhances performance by enabling real-time, two-way communication between clients and servers. It efficiently keeps connections open, reducing latency and improving memory usage compared to traditional HTTP requests.

// Example of a WebSocket server implementation in PHP using Ratchet use Ratchet\MessageComponentInterface; use Ratchet\ConnectionInterface; class Chat implements MessageComponentInterface { protected $clients; public function __construct() { $this->clients = new \SplObjectStorage; } public function onOpen(ConnectionInterface $conn) { $this->clients->attach($conn); } public function onMessage(ConnectionInterface $from, $msg) { foreach ($this->clients as $client) { if ($from !== $client) { $client->send($msg); } } } public function onClose(ConnectionInterface $conn) { $this->clients->detach($conn); } public function onError(ConnectionInterface $conn, \Exception $e) { $conn->close(); } }
