delete cookie in php

Question

I am trying to delete a cookie.

I am using setcookie(\"PHPSESSID\", \"\", time() - 6400); which deletes the cookie just fine.

However it is not enti

Answer 1

using setcookie("PHPSESSID", "", time() - 6400); expires the cookie like 2 hours ago, try using setcookie("PHPSESSID", "", 1); to expire it at epoch January 1st, 1970.

if that doesn't work you can try adding in the path like this setcookie("PHPSESSID","",time()-6400,"/");

You can try this example from http://www.php.net/manual/en/function.setcookie.php#73484 to remove all cookies, but I'm since this seems to be some sort of supercookie who knows..

// unset cookies
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, '/');
    }
}
