Your code is filled with XSS vulnerabilities and should not be used in any production environment. — Daniel Papasian, Sep 17 '08 at 17:49

ksort($_GET);

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

`ksort()` will indeed do the job, but it is not advisable to modify POST/GET variables, even if it is only to re-order them. A workaround would be `$get = $_GET;` then manipulate the custom array instead. – rybo111 Mar 08 '16 at 11:19

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

Posting a hurried link to the documentation perfectly represents how FGITW answers were bad for Stack Overflow and its researchers during the early years. This answer lacks generosity. – mickmackusa Feb 19 '23 at 21:34

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/>';
}
