[Resolved] Simple HOWTO question

[zzz]

How can I check is certain variable is attached to a URL?

Say, I need to write a condition:

if mypage.php?valueXYZ=1

do one thing and is URL doesn't include valueXYZ in the string

do another...

I know ho to check if it's set, but how to check if it's UNSET?

what about:

if($_GET['valueXYZ'] == "")
{
// do action when param unset
}

If it's NOT set then it's UNSET

if (!isset($_GET['valueXYX'])) {

do something if its not set

}
