An app to keep count of currently active users? [closed]

Question

I'm thinking about making a PHP app that would store the IP addresses of people currently visiting my website by keeping them in a database.

I was wondering if someone else has done it before, it's such a common thing that I think someone else has probably done it before.

Very simple script, you can make it much better but this should do it.

<?php

// Make a MySQL Connection
mysql_connect("localhost", "sqluser", "sqlpass") or die(mysql_error());
mysql_select_db("test") or die(mysql_error());

// Insert a row of information into the table "example"
mysql_query("INSERT INTO example (IP) VALUES("."'".$_SERVER['REMOTE_ADDR']."'".") ")
or die(mysql_error());  

echo "Data Inserted!";

?>
