Register Globals Query

I have a register globals query and apologise if I am going over old ground, but I have not been able to clarify my issue in the archives. I am in the process of updating a CMS I had written (but havent coded in 2 years). Please excuse whast may seem like basic questions I have two queries. Switch functions now work by using $_GET['action']. I thing I am unclear about is in order to refer to a case do you still refer to it in the url? switch ($_GET['action']) { default: echo "<a href=\"admin.php?action=Test\">test</a>"; break; case "Test": echo "yep"; break; } (This works! I am not sure if I am missing the point about having register globals turned off) The next issue is how to refer to a second variable within this scenario. My pre php 4.3 url would look like admin.php?action=Test&variable=123 It would seem that I would want to use $GET for both 'action' and 'variable', but all my attempts to call 'variable' in the above example dont seem to work. Any help would be much appreciated.
