What are the limitations of PHP in creating real-time communication interfaces for online gaming compared to languages like C/C++?

PHP is not as efficient as languages like C/C++ when it comes to real-time communication interfaces for online gaming due to its slower execution speed and lack of low-level control over hardware resources. One way to improve real-time communication in PHP is to use WebSocket technology, which allows for bidirectional communication between the client and server in real-time.

// Example PHP code using WebSocket for real-time communication
// This code uses the Ratchet library for WebSocket implementation

use Ratchet\Server\IoServer;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
use YourApp\YourWebSocketClass;

require 'vendor/autoload.php';

$server = IoServer::factory(
    new HttpServer(
        new WsServer(
            new YourWebSocketClass()
        )
    ),
    8080
);

$server->run();
