get session_id() right away? not working...

[dj-kenpo]

Hello,

 

I'm trying to generate and then get the session id right away as I'd like to put it in a databse right away as well upon inital page view, but I clearly don't understand sessions as this is not working

 

<?
session_start(); 

$_SESSION['visitor']=session_id();
$visitor_session_id = session_id();

?>

 

this only works AFTER I refresh the page I need to get it right away though

 

 

thanks

this didn't work either

 

if(!session_is_registered("visitor_session_id")){
$visitor_session_id=session_id();
session_register("visitor_session_id");

print "$visitor_session_id";
