how to expire the session variable

[iffoiffy]

Hi,

I set the session variable doing the following

$_SESSION['emailaddress'] = $email;

When user log out i want to expire that variable, how can i do that?

thanks

unset($_SESSION['emailaddress']) ;
session_destory() ;

I never set a goal because u never know whats going to happen tommorow.

Typo:
session_destroy() is the correct function.
Another way is to use unset($_SESSION) or set $_SESSION = array();
Either way works by wiping out the content of the session. A file may be still in existence until the garbage collection mechanism cleans it up.

I am able to destroy the session variable doing following , but I get this ugly loooking warning. I don't know how to get ride of that.....

<?php
session_start();

unset($_SESSION['wholeseller_grade']) ;
session_destroy() ;

?>


*************
Warning: session_destroy() [function.session-destroy]: Trying to destroy uninitialized session in c:\websites\sntradersonline22\sntradersonline.com\logout.php on line 5

Just put a conditional on it:

if ($_SESSION) session_destroy();
# or suppress the warning
@session_destroy();
