How to get key from search string?

Copy linkTweet thisAlerts:
Jan 27.2011

I have string within URL like:
index.php?ae=ß&q=google&x=0&y=0&cnt=3

I like to get $key[1].
Result is q.

How to get this?

$terms = $_GET[q]; is for value but how to get just [B]q[/B]?

<?php

$i=0; // start counter

$keytofind = 1; // the position we want to find the key for

$key = ''; // the key

foreach($_GET as $k => $v){

if($i == $keytofind){$key = $k;}

$i++;

}

<?php

$keys = array_keys($_GET);

echo $keys[1];

?>

Success!
