PHP: how to get most clicked link?

I'm developing a web portal containing hyperlinks to various sites. I need a PHP solution to keep track the number of visit for each site and then move them to most-visited-sites section. So how do I know when a link get clicked? If you only know non-PHP solution I will need detailed hint, 'cause PHP is my only knowledge.
Thnx in advance

You'll have to use a link to a "middle-man" page. The link would be like http://www.yoursite.com/record.php?i...oothersite.com and for each link you'd have a different ID. Depending on what ID is passed to that page, you update a record in a database. The record with the highest number is the most visited. After you update the record, send them on to the destination which is in your POST/GET array using

Code:

---

header("Location: http://www.example.com/")

---

, but make sure you do that before anything else gets sent to the header.

i got the idea, thnx a bunch
