Answer 1

ksort($_GET);

This should sort the $_GET array by it's keys. krsort for reverse order.

Answer 2

what you're looking for is ksort. Dig the PHP manual! ;)

Answer 3

To get a natural sort by key:

function knatsort(&$karr){
    $kkeyarr = array_keys($karr);
    natsort($kkeyarr);
    $ksortedarr = array();
    foreach($kkeyarr as $kcurrkey){
        $ksortedarr[$kcurrkey] = $karr[$kcurrkey];
    }
    $karr = $ksortedarr;
    return true;
}

Thanks, PHP Manual!

foreach ($_GET as $key => $value) {
 echo $key.' - '.$value.'<br/>';
}
