What are the potential pitfalls of using session_id() and SID in PHP?

Using session_id() and SID in PHP can potentially expose session IDs in URLs, making them vulnerable to session fixation attacks. To prevent this, it is recommended to use session_regenerate_id() to generate a new session ID after a user logs in or performs any sensitive actions. 

// Start the session
session_start();

// Regenerate session ID
session_regenerate_id(true);
