跨子域的Codeigniter会话

I have multiple subdomains and i'm trying to use the sessions across subdomains.

http://example.com
http://subdomain.example.com

I have also set the cookie domain in config.php

$config['cookie_domain'] = ".example.com";

The session userdata and also flashdata are empty when used in the other domain. Im using the same session table as well for both CI instance

我有多个子域,我正在尝试跨子域使用会话。

  http://example.com 
http://subdomain.example.com 
   
 
 

我还在config中设置了cookie域。 php

  $ config ['cookie_domain'] =“。example.com”; 
   
 
 

会话用户数据 在其他域中使用时,flashdata也是空的。 我同时使用相同的会话表用于CI实例

    From the following solution : Sharing sessions

    Both the cookie_domain and cookie prefix has to be set

    $config['cookie_domain'] = ".example.com";
    $config['cookie_prefix'] = "example_";

    first floor is right ,but does not clearly the reason

    Reasons: from: https://ellislab.com/forums/viewthread/131851/#651233

    CI’s session, like any other session mechanism, uses a cookie to identify the session. It’s is the cookie that should be available cross-domain.

    For domain, you need to specify ‘.domain.com’, not ‘*.domain.com’.

    Only $config['cookie_domain'] part is required, $config['cookie_prefix'] is only to make things clean or you have some sub domain uses same domain but does not wanted to be shared.
