嗨，我编写了一个与 facebook 连接并注册用户的代码，然后它使用户登录，一切都很好。.当他们登录时，我设置
$_SESSION['id']
我的猜测是，如果未设置此设置，用户将从我的网站注销，并且不会“自动重新连接”。
因为以前它就像一个循环，每次我注销时，它都会使用 facebook 连接再次登录，即使用户没有再次点击“使用 facebook 登录”...
编辑：我更改了条件并且知道不是“循环”我可以注销该网站。
但是 Session 并没有被取消设置！为什么，只是 cookie 设置为 '' 但是，=( 会话没有被取消设置
这是我的代码

最重要的。注销操作
function logout_action()
{
$srv_nms=BASE;
$srv_nms=str_replace("http://","",$srv_nms);
$srv_nms=str_replace("https://","",$srv_nms);
$srv_nms=str_replace("www.","",$srv_nms);
$srv_pats=$srv_nms;
$srv_nms_arr=explode("/",$srv_nms);
$srv_nms=$srv_nms_arr[0];
$srv_pats=str_replace($srv_nms."/","",$srv_pats);
setcookie(COOKIE_LOGINID,"",0,"/".$srv_pats,$srv_nms);
setcookie(COOKIE_USERNAME,"",0,"/".$srv_pats,$srv_nms);
setcookie(COOKIE_PASSWORD,"",0,"/".$srv_pats,$srv_nms);
unset($_SESSION['user']);
unset($_SESSION['id']);
unset($_SESSION['fb_540341239342331_code']);
unset($_SESSION['fb_540341239342331_access_token']);
unset($_SESSION['fb_540341239342331_user_id']);
header("Location: ".$this->make_url("user/login/l"));
die;
}
会话取消设置并销毁，经过测试但不起作用..为什么？
代码
function logout_action()
{
$srv_nms=BASE;
$srv_nms=str_replace("http://","",$srv_nms);
$srv_nms=str_replace("https://","",$srv_nms);
$srv_nms=str_replace("www.","",$srv_nms);
$srv_pats=$srv_nms;
$srv_nms_arr=explode("/",$srv_nms);
$srv_nms=$srv_nms_arr[0];
