logging user out when they leave site

bike5

How can I log a user out automaticly when they leave my site, BUT still have the same broswer open? So if they have 1 window open and leave my site and then try to reenter my site like on their profile I want it to tell them they were logged out and take them back to the log in page. I can do everything except I am not sure how to automaticly log someone out when they leave my site but still keep the same broswer window open. If anyone could either give me a hint to a url that answers this or some code or just what I have to do exactly that would be great. Thanks a lot in advance.

When the user logs in set a session. Then make it to where when they leave that certain page, it will destroy_session();

You might be able to get javascript to do the page exit thing.

But if I destroy the session when they leave any page how can I carry my session vars to pages when they are just clicking from page to page like normal because it will destroy my session each time. So wouldn't it log them out every page they click on?

I'm sure there is a way around it, but why do you want to do it that way anyways?

I know that if you use $PHP_AUTH_USER and $PHP_AUTH_PASS
(I believe those are the fileds), then it will for sure log out the user when they close the browser, but don't think it will if they just visit another page.

A possible way around this is:

I want to track a users time spent on my page and if they leave my site and go to another site. I think it must have to be a javascript thing because thinking about it when they leave the site I can check that with javascript and then have the javascript execute php code to calculate and update the database with there time spent on the site. Ill just have to play around with that for a little. Thanks for the help.
