isset confusion...how to show a region on a page depending on whether a querystring value exists or not?

If a querysting has a certain value, I can do the following:

<?php if (isset($_GET["nameofqs"]) && $_GET["nameofqs"] == "Test") { ?>
Show this
<?php } else { ?>
Show something else
<?php } ?>



Or, if it's an integer value:

<?php if (isset($_GET["nameofqs"]) && $_GET["nameofqs"] == 1) { ?>
Show this
<?php } else { ?>
Show something else
<?php } ?>



How do I amend the above to display content based on whether or not a querystring actually exists in the URL?

This doesn't work....

<?php if (isset($_GET["nameofqs"]) && $_GET["nameofqs"] == "") { ?>
Show this
<?php } else { ?>
Show something else
<?php } ?>



Neither does this....

<?php if (isset($_GET["nameofqs"]) && $_GET["nameofqs"] != "") { ?>
Show this
<?php } else { ?>
Show something else
<?php } ?>



Hope you can help. Thank you.

This should work:

php:
<?php if (isset($_GET["nameofqs"])) { ?>

     Show this
<?php } else { ?>
     Show something else
<?php ?>
