function NativeSessionStorage::setSaveHandler

Registers session save handler as a PHP session handler.

To use internal PHP session save handlers, override this method using ini_set with session.save_handler and session.save_path e.g.

ini_set('session.save_handler', 'files'); ini_set('session.save_path', '/tmp');

or pass in a \SessionHandler instance which configures session.save_handler in the constructor, for a template see NativeFileSessionHandler.

Throws

\InvalidArgumentException
