Ending a session and deleting cookies

[Logical1]

I am trying to make a log in/log off for my site I have problems with logging off.

I want to set cookies (username) for duration of session and clear it when they log off.

I can resigster a session and set cookie by this code:

 

session_start();

session_name("H1000");

session_register("LUN");

setcookie("LUN",$_POST["N1"],0, "/","www.123xyz.com",0);

 

So far so good.  Problem is that no matter what I try I can not get rid of the username cookie when I try to log off (I can still see the name on pages after I try to log off).

To log off this is the code:

 

<?php

session_start();

$_SESSION = array();

setcookie(session_name(H1000), '$LUN', time()-42000, '/');

session_destroy();

header('Location:index.php');

?>

 

Can somebody tell me what am I doing wrong?

Thanks in advance.

Because of how you're setting the cookies, it looks as if they'll never be set long enough to be deleted.

 

setcookie("HCC","1",0,  "/","www.123.com",0);

 

The third parameter here is the date of expiration as a UNIX timestamp. You have 0, so, if I'm not mistaken, the cookie is deleted as it's set.

 

Try this:

 

setcookie("HCC","1", time()+42000,  "/","www.123.com",0);

Shouldn't killing it be more like this

<?php
session_start();
$_SESSION = array();
setcookie(session_name("H1000"), '', time()-42000, '/');
setcookie(session_name("LUN"), '', time()-42000, '/');
session_destroy();
header('Location:index.php');
?>

I don't follow you.  If the cookie was deleted then after logging in I should not be able to see username (which I do).

(Also I was editing the question when you answered please look at it now).

Can somebody write or point to an example code where session is registed and one cookie is set and then in a secondary page session is ended and cookie cleared?

I have been going over php.net and many forums to see examples and tried at least a dozen of them.  Bless their hearts, often they don't try their code before posting it.

Thanks
