* @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
