who is online

Anon

do you know a way to write a script to tell me who of the users are online?
when a users is logging in, i create a cookie in his computer whith his username in a $username variable.
is there a way to check in the server which $username variables are setted? like setting an array $username[$i]

Thanks!

Keep a table or file that records the username and what time they log in. Each time that they register activity then update the information. There's no sure fire way to know when they've left your site so most people just have an idle limit (30 minutes or so) for when they mark people as being 'away'.

i have to have the cookie set for five hours, so i can't do something like that. I have a log out function but i can't rely on this.
thanks anyway.
Any other solution?

cant javascript do this?

on window.close(execute this script)

Just a guess.

i don't know enough about javascript?
is there a command on window.close in javascipt? do you know how i could write the whole javascript code to call a abcd.php in window.close?
it would be great if i could do that.

I dont know m8 it was a total guess.

You'd prolly just be better off using sessions and timeouts as previously mentioned.

Hi,

Yes, you should be able to call a javascript function or open a page when the user closes the browser. However, this will not cover the case where the user does not click logout, does not close the window, but just types in a new URL.

I am not an expert either with JavaScript but I am sure this command exists.

Thanks,
Victor.

i thought something.
with cookies i can check if $username is set only by the transaction with the specific client.

With <b>Sessions</b> can i check all the $username[$i] who is set and so the users are logged in?

Because with the session the variable is set in the server.

If i could do that i would set an array $username[$i]
and for($i<0...

Does anybody kno that?
