Monitor link clicks

Hi there,

I was wondering if anyone uses a nice php link tracking script?

I'm looking for something which will track click-throughs and report back on the statistics.

For example;

* Create a unique tracking link that redirects to a specific URL
* Monitor impressions and unique clicks against the URL within certain date range stats.

That's pretty much it. We use OpenX for a different project but I don't want something that sophisticated for this. Any thoughts?
