What are the potential security risks of using PHP to manage session IDs in a frameset environment?

Potential security risks of using PHP to manage session IDs in a frameset environment include the possibility of session fixation attacks, where an attacker can set a user's session ID to a known value and hijack their session. To mitigate this risk, you can regenerate the session ID whenever a user logs in or changes their privilege level. 

// Regenerate session ID when user logs in or changes privilege level
session_start();
if(isset($_SESSION['logged_in']) && $_SESSION['logged_in'] === true) {
    session_regenerate_id();
}
