How can session IDs be securely transmitted via URLs in PHP to ensure proper access control for different pages within a website?

Session IDs should not be transmitted via URLs in PHP as it poses a security risk. Instead, session IDs should be stored securely on the server side and only accessed through cookies. This ensures proper access control for different pages within a website and prevents session hijacking. 

// Start a secure session
session_start();

// Set session cookie parameters
$cookieParams = session_get_cookie_params();
session_set_cookie_params(
    $cookieParams["lifetime"],
    $cookieParams["path"],
    $cookieParams["domain"],
    true, // Secure flag to ensure cookies are only sent over HTTPS
    true // HttpOnly flag to prevent access from JavaScript
);

// Generate a unique session ID
session_regenerate_id(true);
