Unable to destroy session in main domain from subdomain

Question

My domain name domain.com and sub-domain is user.domain.com

If I logged in from domain.com then its working fine. I am getting all the session data in my user.domain.com . While I am logout from user.domain.com my main domain domain.com still logged in. If I refreshed main domain. Again session set in my user.domain.com .

I want to destroy session from all the parent and child domain when click logout from my user.domain.com sub-domain.

Yesterday, I have posted forum in here:

NB: I would like to know this in core php not Yii framework. If anyone also know in Yii you can post answer here.

Answer 1

You simply need to destroy session from both domain. domain.com and user.domain.com are two different entities.

If that doesn't work, try unsetting the keys before destroying the session.

For example: unset($_SESSION['id']) , The id will be removed from the $_SESSION .
