Question

I have a SESSION that supports about 80 users, I want to print all their usernames and refresh the page every 60 seconds or so. I know how to refresh the page but <?php print_r($_SESSION['username']); ?> is only printing the username associated with my personal session.

Answer 1

Unfortunately sessions variables don’t work like that.

For you to track each session, one method would be to log each login/connection to a MySQL table with a time stamp attached to it.

Then on your tracking page, have it delete the inactive users, then select the rest:

ie

mysql_query("DELETE FROM sessions WHERE time < " . time() - 60);

$result = mysql_query("SELECT * FROM sessions");

while ($row = mysql_fetch_assoc($result)) {

    echo $row['username'] . "<br />";
}

Then toss in a <meta http-equiv="refresh" content="60"> to refresh the page ever minute.
