How can the PHP script be modified to ensure proper handling of livestream requests for different devices like iPhone, iPod Touch, or iPad?

To ensure proper handling of livestream requests for different devices like iPhone, iPod Touch, or iPad, the PHP script can be modified to detect the user agent of the incoming request and serve the appropriate stream based on the device. This can be achieved by checking the user agent string and redirecting the request to the corresponding stream URL for the specific device.

<?php
$user_agent = $_SERVER['HTTP_USER_AGENT'];

if (strpos($user_agent, 'iPhone') !== false || strpos($user_agent, 'iPod') !== false || strpos($user_agent, 'iPad') !== false) {
    // Serve livestream for iOS devices
    header('Location: ios_livestream_url');
    exit;
} else {
    // Serve default livestream for other devices
    header('Location: default_livestream_url');
    exit;
}
?>
