Katherine's been asking me similar questions all day!

Assuming register globals is turned off in your php.ini file, where ever that may lie, 

Try :

$_GET['variableName']

or 

$_POST['variableName']

$_GET and $_POST are global arrays. There is also $_ENV, $_SESSION and $_SERVER I believe, but I've not used PHP lately, so may be wrong.


If register globals was on, then PHP would automatically populate $variableName for you to use (i.e no Array stuff needed). This caused quite a lot of security problems with people writing rubbish scripts, so it's been turned off by default since about v4.0


Thanks
