How can third-party services like Pusher be integrated into PHP applications for real-time data updates?

To integrate third-party services like Pusher into PHP applications for real-time data updates, you can use the Pusher PHP library. This library allows you to interact with Pusher's API and send real-time messages to clients subscribed to specific channels.

// Include the Pusher PHP library
require_once('path/to/Pusher.php');

// Set your Pusher credentials
$options = array(
    'cluster' => 'YOUR_CLUSTER',
    'useTLS' => true
);
$pusher = new Pusher(
    'YOUR_APP_KEY',
    'YOUR_APP_SECRET',
    'YOUR_APP_ID',
    $options
);

// Trigger an event on a specific channel
$pusher->trigger('channel_name', 'event_name', array('message' => 'Hello, world!'));
