It's pretty rare that you REALLY want to blindly copy ALL $_GET arguments,
but you can:
$get = '';
reset($_GET);
while (list($k, $v) = each($_GET)){
$get .= "&k=" . urlencode($v);
}
$get[0] = '?';
But you should *PROBABLY* be checking for specific values in $_GET, making
sure they are "clean" and passing on only those values.
$kosher = '[^A-Za-z0-9\'"\\. ,-]';
$name = $_GET['name'];
$zip = $_GET['zip'];
$zip = (int) $zip; //Assuming only 5-digit zip code will ever be used in
this application
$zip = sprintf("%05s", $zip);
$name = preg_replace($kosher, '', $name);
$url = "?name=" . urlencode($name) . "&zip=$zip";
