Destroying session variables

[samved]

Hi,

 

I am facing problems in destroying the session variables in my logout file  :'( .I have used session_id() in my php files for ex $sid = session_id().Now when I click on logout I naviagte to my index file but the session variable $sid still remain.I have chkd it.I have kept session_start() function in a file and I am including that file in every php by require_once function.The file is palced in Includes folder..is it causing the problem?? Plz help me out

 

Also can I use session_start() more than once in a single php file?

 

My logout file is :

 

<?php

        session_start();

session_destroy();

header("location:index.php");

exit();

?>

session_destroy() only erases the data stored within the current active session. If you want a new session id to be generated when the user logs out you'll need to use session_regenerate_id.

Thanks a lot for your reply, the solution worked for me.Is there any way I can destroy old session Id instead of regenerating it?

What are you wanting to with the session id when your destroy the session. The id will never be unset, session_id will always return the id of the current active session, even after calling session_destroy.
