Answer 1

You could use:

<?
$params = $_GET;
$params['lang'] = 'EN';
$qs = '?';
foreach($params as $k=>$v)
  $qs .= $k.'='.urlencode($v).'&';
$url = substr($_SERVER['PHP_SELF'].$qs, 0, -1);

echo $url; //EN

$params['lang'] = 'FR';
$qs = '?';
foreach($params as $k=>$v)
  $qs .= $k.'='.urlencode($v).'&';
$url = substr($_SERVER['PHP_SELF'].$qs, 0, -1);

echo $url; //FR
?>
