how to use apache sessions to make a user online list

mc_bobby

Hi i've been programming in perl for about 2 years now and found out php is MUCH better with the type of programming i do. I was wondering how i can use apache sessions in php to keep track of the users that are crrently on my site. im new to php so please forgive me for not understanding allot. I got this script at http://hangoutspot.com/phps/test.php which uses session in php.. what it does, is it saved the session id in a cookie and then using that to featch info out of the session. if i close the browser the cookie dies. Using that scritp how would i be able to find out who is still on my website, sort of like a user online lsit ? thanks for all the help yo guys can give me

i attached the scirpt that is used in test.php

you should build your own session programs, which store the data in database or your folder and dose not expire for 15 min.
now you can run a query and ask for users which are greater time from now time, collect the number of users and display it.

function show()
{
echo "Variables set in current session:<br />\n";

            if( isset($GLOBALS['_SESSION']) ) $a = $GLOBALS['_SESSION'];
            while( list($key,$value) = each($a) )
                echo "Variable: $key - Value: $value<br />\n"; 
    }

this is part of a session scritp i downloaded frm this site.. now im wondering how does it get the session id to check the vaules in the session, because i know the site gives me a cookie when i start a session, and how can i modify it to use the url string session id like this /?session=7024079db0c73c9827410f94c256e0dd and make it use that incase the user does not support cookies
