PHP cannot unset cookie

Question

I have problem in my code.

I have tried to search on the right columns some answers that can help me, but i didn't found.

This is my inset code:

<?php
    if(isset($_POST['**'])) {
        $set_time_out = 60;
        setcookie("***", "username", time()+60, "admin");
    }
?>

now, my unset code is:

if(isset($_GET['**']) == '***') {
    unset($_COOKIE['***']);
}

and when i get in to the "get" link, nothing happened.

the cookie still exists.

help, please :)

EDIT

The login code is..

<?php if(isset($_POST['*'])) { $set_time_out = 60; setcookie('***', '**', time()+60, 'admin/'); } ?>

And my "logout" code is :

`

if(!$_COOKIE['***']) {
    echo "<meta http-equiv=\"refresh\" content=\"0;url=../login.php\">";
}

if(isset($_GET['**']) == '******') {
    setcookie('***', '', time()-60, 'admin/');
}

?>`

It is not +60 but -3600. Look more carefully. – Andras Toth Mar 28 '13 at 13:36

the one thing that everybody here has ignored and should have brought up is the fact that cookies have a domain and path ad well. if setcookie('cookiename','',1); doesn't work, you need to make sure the path and domain are correct too. setcookie('cookiename','',1,cookie_path, cookie_domain) – ejfrancis Jun 03 '14 at 21:55

set cookie in the past... like:

setcookie ("***", "username", time() - 3600);

to unset cookie, you need to set your expire time to the past, like.

setcookie('your_cookie_name', '', time()-3600);

To delete a cookie always set its time in negative from the current time().

setcookie('nameofcookie', '', time()-3600);

This code sets your cookie persist time to negative so it automatically deletes.
