Are PHP sessions vulnerable to manipulation by clients?
PHP sessions can be vulnerable to manipulation by clients if the session ID is not properly protected. To prevent this, developers should use session_regenerate_id() to generate a new session ID after a user logs in or changes privilege levels. This will help mitigate the risk of session fixation attacks.
// Start the session
session_start();
// Regenerate the session ID
session_regenerate_id();
