user online.. help

[insanemonkey]

I have asked this question before and got no anwser...

What I am trying to do is show if the user is online like myspace has it..
I use sessions and was wondering what I could do to make this happen..
I can't find any tutorials out there for this..

in my sessions I have this.



function startSession(){
global $database; //The database connection
session_start(); //Tell PHP to start the session

$this->logged_in = $this->checkLogin();

/* Update timestamp */
else{
$database->addActiveUser($this->username, $this->time);
}



what that does it checks user online then update timestamp, I was wondering how I could user this in order to show(when a user visits a users profile) them online.

any help please,...

Have a list populated at login and cleared of any old ones with each use of the script.

can you give me example. what do you mean have a list populated, also

I have a online script that shows users online if this is any help..


<?
if(!defined('TBL_ACTIVE_USERS')) {
die("Error processing page");
}

$q = "SELECT username FROM ".TBL_ACTIVE_USERS
." ORDER BY timestamp DESC,username";
$result = $database->query($q);

$num_rows = mysql_numrows($result);
if(!$result || ($num_rows < 0)){
echo "Error displaying info";
}
else if($num_rows > 0){

echo "<table align=\"left\" border=\"0\" cellspacing=\"0\" cellpadding=\"3\">\n";
echo "<tr><td><font size=\"2\">\n";
for($i=0; $i<$num_rows; $i++){
$uname = mysql_result($result,$i,"username");

echo "/ <a href=\"login/userinfoo.php?user=$uname\">$uname</a> ";
}
echo "</font></td></tr></table><br>\n";
}
?>


it may be to some use...
