无法在PHP中销毁会话和cookie(Fail to destroy session and cookies in PHP)

无法在PHP中销毁会话和cookie(Fail to destroy session and cookies in PHP)

目前我使用以下代码将用户注销。

session_start(); setcookie("u", "", time() - 999999); setcookie("i", "", time() - 999999); setcookie(session_name(),"",time()-999999); session_destroy();

$_COOKIE['u']和$_COOKIE['i']用于自动登录用户。

我的问题是当我将这个注销文件直接放在web目录下（即www/ ）时，它运行得很好。 但是，当我将它放在辅助目录（即www/includes/ ）或将这些代码与其他PHP页面（即更改密码然后登录用户）组合在includes文件夹中时，用户无法成功注销。

Currently I am using the following code to log users out.

session_start(); setcookie("u", "", time() - 999999); setcookie("i", "", time() - 999999); setcookie(session_name(),"",time()-999999); session_destroy();

$_COOKIE['u'] and $_COOKIE['i'] are used to automatically log in users.

My problem is when I put this logout file directly under the web directory (i.e. www/), it works very well. However, when I put it in the secondary directory (i.e. www/includes/) or combined these codes with other PHP pages (i.e. change password and then log user out) in includes folder, user is not able to log out successfully.

看起来你的cookie被设置在不同的路径上。 第4个参数是域路径，第5个是域。

bool setcookie ( string $name [, string $value [, int $expire = 0 [, string $path [, string $domain [, bool $secure = false [, bool $httponly = false ]]]]]] )

见http://www.php.net/manual/en/function.setcookie.php

在使用cookie时明确设置这些是个好主意。

It seems like your cookies are being set on different paths. The 4th parameter is the domain path and the 5th is the domain.

bool setcookie ( string $name [, string $value [, int $expire = 0 [, string $path [, string $domain [, bool $secure = false [, bool $httponly = false ]]]]]] )

See http://www.php.net/manual/en/function.setcookie.php

It's a good idea to explicitly set these when working with cookies.
