As of PHP 4.1.0, you no longer need to use session_register(); you can
simply add items to the $_SESSION superglobal array:

$_SESSION['nfo'] = $nfo;

Visit http://php.net/session for more information.

> $sn=session_name();
> $nn=session_id() ;
>
> $web="page2.php?lang=en";
> $web.="&$sn=$nn";
>
> header("Location: $web");
> ?>
> ===============
> page2.php:
> <?
> session_start();
> global $nfo;

This only works if you have register_globals on -- which you probably
shouldn't. A better, more portable way to do this would be:

$nfo = array();
if (isset($_SESSION['nfo'])) {
$nfo = $_SESSION['nfo']
}

> $uss=$nfo["fu"];
>
> echo $uss; //// HERE $uss is empty!

You should probably check for the existence of the 'fu' key in the array
before doing this.

$uss = null;
if (isset($nfo['fu'])) {
$uss = $nfo['fu'];
}

if (empty($uss)) {
echo "Missing vital session info";
die;
}

echo $uss;

I've pointed out my recommendations above.
