如何在一次登录下连接两个Web应用程序？

Question

I have created two very different web applications using Yii. They both share the same database and they both use the same tables to log in. Both web applications have a link towards each other. What I'm trying to achieve is if a user happens to login to any of the apps (let's say app 1), they can transfer from app 1 to app 2 without having to login and vice versa.

I looked for session initiation and I researched that it should be found in UserIdentity.php but when I checked, there were no sessions being initiated at all. I'm not going to post code for now since the codes are working fine, it's just that I need to know how to make the user experience more flowing.

If the applications are on the same server, you can follow this article. Basiclly you have to set the same (cookie) for both applications, and set a session path. You can also save the sessions to a database table (See Larry Ullman's article on this) as an alternative.
