What are the potential challenges or pitfalls when trying to display live logging from a PHP script on a web interface?

Potential challenges when displaying live logging from a PHP script on a web interface include ensuring real-time updates, handling large amounts of data efficiently, and maintaining security by preventing unauthorized access to the logs. To address these challenges, you can use technologies like WebSockets for real-time updates, implement pagination or lazy loading for handling large data sets, and restrict access to the logs using authentication and authorization mechanisms. 

<?php
// Implementing WebSockets for real-time updates
// Example code using Ratchet library (https://github.com/ratchetphp/Ratchet)

require __DIR__ . '/vendor/autoload.php';

use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;

class LiveLogServer implements MessageComponentInterface {
    protected $clients;

    public function __construct() {
        $this->clients = new \SplObjectStorage;
    }

    public function onOpen(ConnectionInterface $conn) {
        $this->clients->attach($conn);
        echo "New connection! ({$conn->resourceId})\n";
    }

    public function onMessage(ConnectionInterface $from, $msg) {
        // Handle incoming messages (e.g., log updates)
    }

    public function onClose(ConnectionInterface $conn) {
        $this->clients->detach($conn);
        echo "Connection {$conn->resourceId} has disconnected\n";
    }

    public function onError(ConnectionInterface $conn, \Exception $e) {
        echo "An error has occurred: {$e->getMessage()}\n";
        $conn->close();
    }
}

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

$server->run();
