One URL parameter without a name

[james909]

My site currently uses one parameter in the URL like this:

 

http://www.mydomain.com/folder/?paramname=AB32123

 

I would like to remove the parameter name, so the URL is:

 

http://www.mydomain.com/folder/?AB32123

 

How would I then call use this parameter,

currently I use $_GET['paramname'] but without a name I am unsure how

 

I have tried:

$_GET

$_GET[]

 

but they both through up errors?

 

what is the correct way to get this paramter without a name

[requinix]

$_SERVER["QUERY_STRING"]

 

If you look hard at $_GET you'll see it has $_GET["AB32123"] = "" but don't try to use that.
