- * for newly created session.
- *
- * @global bool $session_exists Whether a session with the given id already exists
- * @global int $session_expire Session expiration delay in seconds
- * @param string $id Session ID with format: [a-z0-9]{26}
- * @param string $data Serialized session data
- * @return boolean Returns false if parameters are missing, true otherwise
