Trying to have something load when people first visit site

[jow ga]

I have a script that I want to have show up when people first open up my site and to not show there again until they come back or their session has expired. I am not sure how to use the session data to make this happen.

Something like this generally speaking.

If (!session){show this}

Or is there another better way then using sessions to do it.

 

 

Thanks,

Tom

if ($session_started == false) { echo this }
