Hi there, I have got PHP 5 installed on IIS6 with 'register_globals = on'. When run my page with session variable at top of the page <? $_SESSION['_user'] == "" .......... ?> I got notice like "Notice: Undefined index: _user in E:\Projects\........." What can be the reason and what is the solution? _user variable is not registered before. Thanks a ton for reading this far.
