PHP5 and "isset"

[Westcoast Sheri]

When "register globals" is set to "on," has anyone noticed if PHP
Version 5 affects the usage of "isset" or not?

For example, in a webpage form, should the following code:
if (!isset($ordern umber)) { $ordernumber = '123456'; }

....be changed to this:

if (!isset($orderi d) || $orderid==NULL) { $ordernumber = '123456'; }

Thanks!

Use empty() to be on the safe side.
