You can only access sessions when you know the session id.
Most sites handle online users in their database, store a timestamp each
time a user loads a page. When you want to display the online users, check
where the timestamp is between now and a few minutes ago. Note that without
javascript (or flash/java/etc) there is no way to truly know if the user
left or not. The session will stay active for a long time, depending on
your php.ini settings.

You mean when user logged in i add new record to table and when logged out i
delete the row? So if user close the browser without logout how can i find user
is online or not?

Like Matijn said, unless you're using some kind of client-side method to
continually poll the server, you can't know if they've just closed their
browser. There are Javascript events for exiting a page, but they don't
work correctly on Safari and iOS Safari.
You don't have to actually save anything to the DB manually, just
instruct PHP to use the DB for its own sessions, rather than files.
Do you really need to inspect each visitors session in detail, or do you
just need a way to determine how many unique visitors are on the site at
any one time?
Thanks,
Ash

onbeforeunload works fine in Safari; I use it all the time.

Apparently it has problems when browsing in "porn" mode, and mobile
safari has major problems with it. I'm basing this on previous posts on
forums I've been on, so it might have been fixed now, but I don't know
for sure either way.

PHP sessions is a really bad mechanism to use to accomplish this. In the past
I've used memcached or redis for presence indicators. Both allow you to set
keys that expire after a set period. The problem with this is that a user can
appear to be online for up to "set period" seconds longer than they actually
are.
In the system I'm currently building I've got a node.js daemon to which the
browser connects. That daemon exposes an API that the rest of the system can
call to get lists of online users, which is easily gathered since it's just the
list of connected users. There is then no delay between the browser closing the
connection and the daemon deciding that user is no longer online.
If you have a chat system I'm curious as to how it works, since presence is
usually tied closely to how the client is detecting new messages.

Ah, so you don't need to see the details of the sessions then. Facebook does
this (badly) by using javascript on the client side which triggers an update of
a timestamp on the server, which then allows you to determine who is online (or
was within a given time limit)

Maybe it's bad, but there's no good alternative, except sending ping
requests to your server every second or so, but any site as large as
Facebook will DDOS itself when using things like that ;)

So best way is use a script(javascript) to send ajax to server every 5 second
to check users is logged in or not? Is that okey?
I want to write chat module like facebook and i need a solution to find online
users and way to send messages when users chat together, does any one write
similar module like that?

I'm not saying the method is bad, but the way Facebook does it isn't great, I'm
constantly seeing people online who "sign out" when I open up a message box.
Now that might be genuine, but I'm not *that* unpopular!

Ash

I'm sorry. Were you saying something? As soon as I saw "Ashley Sheridan"
in my email client, it closed and my computer rebooted for some strange
reason. ;-}

Because of the way the list is set up ...
We all get every bounce message as a result of posting to PHP lists since WE are
set as the reply-to address. This apparently is the right way of doing email
lists ;)
