can not delete cookie, it still show up call it in other file

create cookie 

$cookie_name = "userw";
$cookie_value = "John due";
setcookie($cookie_name, $cookie_value, time() + (86400 * 30), "/"); // 86400 = 1 day

if(!isset($_COOKIE[$cookie_name])) {
    echo "Cookie named '" . $cookie_name . "' is not set!";
} else {
    echo "Cookie '" . $cookie_name . "' is set!<br>";
    echo "Value is: " . $_COOKIE[$cookie_name];
}

delete cookie

// set the expiration date to one hour ago
$cookie_name = "userw";

setcookie("$cookie_name", "", time() - 3600);
unset($_COOKIE[$cookie_name]);


$cookie_name = "userw";
if(!isset($_COOKIE[$cookie_name])) {
    echo "Cookie named '" . $cookie_name . "' is not set!";
} else {
    echo "Cookie '" . $cookie_name . "' is set!<br>";
    echo "Value is: " . $_COOKIE[$cookie_name];
}

read cookie after deleted

$cookie_name = "userw";
if(!isset($_COOKIE[$cookie_name])) {
    echo "Cookie named '" . $cookie_name . "' is not set!";
} else {
    echo "Cookie '" . $cookie_name . "' is set!<br>";
    echo "Value is: " . $_COOKIE[$cookie_name];
}

If I read the cookie in the file while with unset, the cookie does not appear. but when I read the cookie again it shows up. I test it in xampp. Does anyone have any solution for this?

When removing the cookie, you need to specifiy the same path that you specified when creating it (unless you want to do very specific things):

Try this:

setcookie($cookie_name, '', time() - 3600, '/');   // note the 4th param, '/'
