Similar to anonymizer script

Basicly what i want to do is make a script that redirect a link i imput in a form to a different site, but what i want to do is make a redirect page that takes 5 seconds to redirect, i allready made something similar using this script, </script>
<script>
setTimeout('window.location.href="http://sharebee.com/c0c27f72"',5000);
</script>
</script>

but how can i make a form that saves it to a mysql database and saves the link like, www.mysite.com/1, www.mysite.com/2 and when every someone clicks that link it takes them to a redirect page where i can put my adverts and popups and den direct them to the website in the mysql database. anything similar to this script that i can obtain from the internet ? or can someone point me to a direction of how i can start this, im kind of a noob on scripting so go easy on me Thank you for reading,
