Sounds like register_globals is set to off (which has been the default
since 4.3 IIRC).

You should be accessing external variables like so:
$_GET['do']
$_POST['do']
$_COOKIE['do']

using whichever super global is appropriate.

If you are not able to do this (eg big project with hundreds of pages of
code etc) then you'd need to set register_globals on for that site.
