Finally, here is the PHP Code:

<?php
//fill in some basic info
$server = "localhost";
$db_user = "username";
$db_pass = "password";
$database = "users";
$timeoutseconds = 300;

//get the time
$timestamp = time();
$timeout = $timestamp-$timeoutseconds;

//connect to database
mysql_connect($server, $db_user, $db_pass);

//insert the values
$insert = mysql_db_query($database, "INSERT INTO useronline VALUES
('$timestamp','$REMOTE_ADDR','$PHP_SELF')");
if(!($insert)) {
     print "Useronline Insert Failed &gt; ";
}

//delete values when they leave
$delete = mysql_db_query($database, "DELETE FROM useronline WHERE timestamp&lt;$timeout");
if(!($delete)) {
    print "Useronline Delete Failed &gt; ";
}

//grab the results
$result = mysql_db_query($database, "SELECT DISTINCT ip FROM useronline WHERE file='$PHP_SELF'");
if(!($result)) {
    print "Useronline Select Error &gt; ";
}

//number of rows = the number of people online
$user = mysql_num_rows($result);


//spit out the results
mysql_close();
if($user == 1) {
print("$user user online\n");
} else {
print("$user users online\n");
