What potential issues can arise when using sessions in PHP?
One potential issue when using sessions in PHP is session hijacking, where an attacker steals a user's session ID and impersonates them. To prevent this, you can use session_regenerate_id() to generate a new session ID on each request.
// Start the session
session_start();
// Regenerate session ID to prevent session hijacking
session_regenerate_id();
