[Resolved] how to see if any $_GET variables are set...

[drstrangelove]

I am hoping one of you can give me a simple solution to this.
I've googled and searched this forum, but I didn't seem to fall upon the right answer.
Is there a quick way to see if any $GET variables have been set?
I can only think of checking the $SERVER['PHP_SELF'] to see if it contains a "?";
Is there a better, cleaner solution?
Thanks

foreach($_GET as $Key => $Value)
{
echo "Key: $Key -- Value: $Value";
$Counter++;
}

There would be a few ways but that will show all get vars. What exactly are you wanting to do?

Counter would give you the total Get vars set.

Consider:

<?php
if (empty($_GET))
	echo 'not set';
else
	echo 'set';
?>

Guys,
Thanks a million for the quick response. Both suggestions worked perfectly.
It turns out that what I wanted to do with that didn't apply, but the information is useful.
Thanks I really appreciate it.
