我正在wordpress上工作，点击注销按钮，用户将使用<?php wp_logout(); ?> 功能当我遵循wordpress网站上的一些指导原则时，我知道它实际上删除了所有cookie，但会话和更新的数据库中的哪个表呢，实际上我正在使用buddypress查看当前活动的用户我得到了销毁cookie的代码。

function wp_clear_auth_cookie() {
    do_action(\'clear_auth_cookie\');

    setcookie(AUTH_COOKIE, \' \', time() - 31536000, ADMIN_COOKIE_PATH, COOKIE_DOMAIN);
    setcookie(SECURE_AUTH_COOKIE, \' \', time() - 31536000, ADMIN_COOKIE_PATH, COOKIE_DOMAIN);
    setcookie(AUTH_COOKIE, \' \', time() - 31536000, PLUGINS_COOKIE_PATH, COOKIE_DOMAIN);
    setcookie(SECURE_AUTH_COOKIE, \' \', time() - 31536000, PLUGINS_COOKIE_PATH, COOKIE_DOMAIN);
    setcookie(LOGGED_IN_COOKIE, \' \', time() - 31536000, COOKIEPATH, COOKIE_DOMAIN);
    setcookie(LOGGED_IN_COOKIE, \' \', time() - 31536000, SITECOOKIEPATH, COOKIE_DOMAIN);

    // Old cookies
    setcookie(AUTH_COOKIE, \' \', time() - 31536000, COOKIEPATH, COOKIE_DOMAIN);
    setcookie(AUTH_COOKIE, \' \', time() - 31536000, SITECOOKIEPATH, COOKIE_DOMAIN);
    setcookie(SECURE_AUTH_COOKIE, \' \', time() - 31536000, COOKIEPATH, COOKIE_DOMAIN);
    setcookie(SECURE_AUTH_COOKIE, \' \', time() - 31536000, SITECOOKIEPATH, COOKIE_DOMAIN);

    // Even older cookies
    setcookie(USER_COOKIE, \' \', time() - 31536000, COOKIEPATH, COOKIE_DOMAIN);
    setcookie(PASS_COOKIE, \' \', time() - 31536000, COOKIEPATH, COOKIE_DOMAIN);
    setcookie(USER_COOKIE, \' \', time() - 31536000, SITECOOKIEPATH, COOKIE_DOMAIN);
    setcookie(PASS_COOKIE, \' \', time() - 31536000, SITECOOKIEPATH, COOKIE_DOMAIN);
}
