Multisite login

[LittleJoe]

If I have a website, say example.com, and I use PHP sessions to store the login details, can I then access the same session from my.example.com and another.example.com? I need a website with subdomains that have different purposes but the user should only have to log in once at the root domain.

Just point the database connection to the same database. There should be no problem with that.

you need to use http://php.net/manual/en/function.session-set-cookie-params.php to set domain of your site and rest of your subdomain will have same same session. Apart from using this on each script you can also change corresponding field in php.ini to do the same thing.

Hello friend, Sessions names must be same for all websites, then all of the websites must be opened in the same browser.then you can get succeeded in the above task.
