How can a PHP developer ensure that a session is unique to each user and not overwritten by another user logging in?
To ensure that a session is unique to each user and not overwritten by another user logging in, a PHP developer can use session_regenerate_id() function to regenerate the session ID whenever a user logs in. This will create a new unique session ID for each user, preventing session hijacking or overwriting issues.
session_start();
// Regenerate session ID to ensure uniqueness
session_regenerate_id();
// Continue with user authentication and session handling
