Questions Regarding Sessions

Hi:

I have the following small php files, t1.php and
t2.php

t1.php contains the ff:
<?
function func1()
{
global $HTTP_SESSION_VARS;
session_start();
$HTTP_SESSION_VARS["test"]="hello";
session_register($HTTP_SESSION_VARS["test"]);
}
?>

t2.php contains the ff:
<?
include("t1.php");

func1();
session_start();
if
session_is_registered($HTTP_SESSION_VARS["test"]){
echo ("Session is registerd <br>");
$x = $HTTP_SESSION_VARS["test"];
echo ("value of session = $x");
session_destroy();
}
?>

The output I am getting when loading t2.php is the ff:
Session is registered
value of session =

Instead of:
Session if registered
value of session = hello

I've tried testing simple session scripts and it
works, but initializing and using sessions in a
function seems to be a problem for me.
The session is registed, but the value of the
session variable is missing. The session is created
when I look at the /tmp directory and the the file
ses<session id>.
How can I make the script above to work?

Some additional info:
version : php 4
important configuration = --enable-track-vars
--enable-trans-sid --with-apache=<directory>

Thank you very much,

ludwig.
