没有设置cookie也会导致我的会话失败

Question

I use this code to unset my cookies (thanks to Stack)

if (isset($_SERVER['HTTP_COOKIE'])) {
    $cookies = explode(';', $_SERVER['HTTP_COOKIE']);
    foreach($cookies as $cookie) {
        $parts = explode('=', $cookie);
        $name = trim($parts[0]);
        setcookie($name, '', time()-1000);
        setcookie($name, '', time()-1000, '/');
    }

but this also unset my $_SESSION. How can that be?

Answer 1

dude session also stored as a cookie value which ends on the termination of the page or browser..

instead of unsetting every cookie be selective

(ie)

if you want to delete cookie named user

setcookie("user", "", time()-3600); //deletes only that cookie

you can see what are the cookies set using the print_r($_COOKIE); function...
