从子域到主域的 PHP 会话变量 [英] PHP Session Variable from subdomain to main domain

问题描述

我在亚马逊 Web 服务器 EC2 实例上的 ISPConfig 中设置了 2 个域/站点，

i Have setup 2 domains/sites in the ISPConfig on amazon Web server EC2 instance,

我有一个名为 app.example.com 的域，另一个是 https://www.example.com两个域都在 ISpConfig3 中设置.所以两者都有单独的 webroot 和代码文件.我在 app.example.com 上设置了一些会话变量，而在 https://www.example.com 上我只有静态内容.但在某些情况下，我需要从 app.example.com 访问会话变量到我的顶级域 https://www.example.com

i have a domain named app.example.com and the other is https://www.example.com Both domains setup in ISpConfig3. so both have separate webroot and code files. I have setup some session variables on app.example.com , while on https://www.example.com i have only static contents. But in some cases i need to access the session variables from app.example.com to my top domain https://www.example.com

我尝试在 http://app.example.com

ini_set('session.cookie_domain', '.example.com' );

session_start();

$_SESSION['user_name']= "my_session";

然后在 https://www.example 上访问 $_SESSION['user_name'].com

and then accessing $_SESSION['user_name'] on https://www.example.com

print_r($_SESSION['user_name']);

但似乎没有任何效果，我怎样才能使它起作用?.

But nothing seems to be working, How can i make this to be working?.

推荐答案

@Alan Gularte 的第一条评论我认为回复得很好.如果它不起作用，您可以考虑自己编写一个cookie来来回传递信息.

The first comment of @Alan Gularte replies quite well I think. If it does not work, you may consider writing a cookie yourself to pass info back and forth.

setcookie ("PassMySessionName", $_SESSION['user_name'], time() - 3600, "/", "example.com");

将 cookie 域设置为example.com"将使其在 www.和应用程序.

Setting cookie domain to "example.com" will make it available both on www. and app.

另一方面，您会在 $_COOKIE 数组中找到它.

On the other side you will find it in the $_COOKIE array.

$PassedUserName=$_COOKIE["PassMySessionName"];

如果您需要在不启用 cookie 的情况下全部工作，它会变得更加复杂，因为 $_SESSION 将透明地将参数附加到您的 url.在这种情况下(如果您从一个站点链接到另一个站点)，您可以手动将它们添加到网址中.

If you need it all to work without cookies enabled, it gets much more complicated, as $_SESSION will work appending parameters to your urls transparently. In that case (if you link from one site to the other) you may add them manually to the urls.
