unset $ _SESSION不工作 [英] unset $_SESSION not working
本文介绍了unset $ _SESSION不工作的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我做了一个与Facebook连接并注册用户的代码，然后使用户登录，一切都很好。当他们登录时，我设置
$ _ SESSION ['id']
我的猜测是，如果这是没有设置的用户将从我的网站注销，它不会自动关联..
因为以前它就像一个循环，每次我注销，它登录再次使用Facebook连接即使用户再次使用Facebook登录...
编辑：我更改条件，知道不是循环我可以注销该站点..
但是，会话，不是没有设置！为什么，只是cookies设置为''但是=（会话未取消设置
这是我的代码

解决方案
不建议取消设置会话变量这样。使用 session_unset（），请参见 http://php.net/manual/en/function.session-unset.php
那么，你不希望会话仍然存在于用户计算机上，为此使用 session_destroy（）。
session_unset（）只是清除会话以供使用。
Hi i made a code that connects with facebook and register the user, then it makes the user login , everything works very nice.. When they login i set
$_SESSION['id']
My guess was, if this was unset the user will be logout from my site, and it wont be "autoreconnected"..
Because previously it was like a loop, everytime i logout, it login again using the facebook connect even if the user havent clic again "login with facebook"...
EDIT: I change a condition and know is not "looping" i CAN logout of the site..
But the Session , is not unset!, why, just the cookies are set to '' but ,=( session is not unset
Here is my code

Session unset & destroy, tested but not working.. why?? Code
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,$srv_nms);
session_unset();
header("Location: ".$this->make_url("user/login/l"));
die;
}
解决方案
It's not recommended to unset session variables this way. Use session_unset(), see http://php.net/manual/en/function.session-unset.php
Over that, you don't want that the session still exists on the users computer, for this use session_destroy().
session_unset()just clears out the session for usage.
