What are the potential issues with using session data in PHP scripts, and how can they be resolved?
Issue: One potential issue with using session data in PHP scripts is the risk of session hijacking or session fixation attacks. This can be resolved by using session_regenerate_id() to regenerate the session ID whenever a user's privilege level changes or upon successful login.
// Regenerate session ID to prevent session fixation attacks
session_regenerate_id(true);
