CI_Session_driver::_fail PHP Метод

_fail() защищенный Метод

Drivers other than the 'files' one don't (need to) use the session.save_path INI setting, but that leads to confusing error messages emitted by PHP when open() or write() fail, as the message contains session.save_path ... To work around the problem, the drivers will call this method so that the INI is set just in time for the error message to be properly generated.
