register globals in php

Hello,

How bad is it to enable register_globals in php?
Does it depend on the usage or is it so bad that it shouldn't be used?
What can possible happen if it's enabled?

Lots can POSSIBLY happen. But what DOES happen depends on what you do to prevent it, not on from PHP, but Apache, your firewalls, and your code itself. This doc: http://www.php.net/manual/en/security.globals.php covers it pretty well.
