PHP4 (How to destroy session variable)!

[Anon]

Hi!
i have a problem with sessions in PHP4.
my doubt is how do i destroy a session variable.
eg:
<?
session_start();
$username="danny";
session_register("username");
//how do i destroy $username;
//i,e if i echo $username;

//nothing should get printed..
?>
thanks and regards...

unset($username) will umm, unset $username =)

I note that there are some oddnesses with session variables, e.g. if you call session_destroy(), the variables registered for the session will still be set for the duration of that request. At least, that is my experience. You have to explicitly call unset().

HTH,

session_unregister ("var_name");
