on in php.ini, rather than explicitly binding variables to
HTTP parameters.

But register_globals is going to be deprecated at some
point.

See attached for an example.

This program should use the get ini setting keyword to
determine if the program uses $_POST/$_GET, then from
that, it should alter how it gets the data.
