Solution

Set the validity period to a previous time.You can delete cookies. Also, @ MarlinMarlin says,

When xdebug is used for debugging, the session still exists.

If PHP's session_start () function is used, a new session is generated, which is irrelevant to the cookie. The cookie debugging method is firebug or chrome dev tool.

Take my website as an example http://justjavac.com/

Http://www.php.net/manual/zh/function.setcookie.php

Set the validity period to a previous time.

setcookie ($auth_cookie_name, "", time() - 3600);
