How can one ensure the proper transmission of session IDs in PHP scripts, particularly when dealing with mobile networks or proxies?

To ensure the proper transmission of session IDs in PHP scripts, especially when dealing with mobile networks or proxies, it is recommended to use HTTPS to encrypt the communication between the client and server. This helps prevent session hijacking and eavesdropping on session data. Additionally, setting the session cookie to be secure and HTTP only can further enhance security. 

// Set session cookie parameters
session_set_cookie_params([
    'lifetime' => 0,
    'path' => '/',
    'domain' => 'example.com',
    'secure' => true, // Ensures the cookie is only sent over HTTPS
    'httponly' => true // Prevents client-side scripts from accessing the cookie
]);

// Start the session
session_start();
