Ok I am posting my 2 day project here in the hope that it can be of some help to someone. This little bit of code could easily be adapted to do a variety of diff things.
Enjoy everyone...

//+******************************************************************+
// .:]Affiliate or Pay Per Click Marketing Cookie Tracker[:. |
// Copyright 2004 Shannon Prue |
// Use of this script is restricted Non-Commercial / Learning |
// Only, If you would like to use this commercially mail me @ |
// Inspiration AT gmail.com for permission. |
// __________________________________________________________ |
// This script in a nutshell will drop 3 cookies on a users |
// computer when they arrive at your website, One to count |
// number of visits the user has been to your website, |
// One to specify how they found your site, and One to show |
// what keywords were used to find your site. This info |
// can later be extracted say during an order process to |
// track marketing campaignes or track affiliate sales. |
// I have added a debug mode to test the cookie proccess, as- |
// well as added comments for easy adaptation. |
// an example a url that would drop all 3 cookies is as |
// follows: example.php?src=ov&kw=my+search+term |
//+******************************************************************+
$visitcount = $HTTP_COOKIE_VARS["visits"];
$url = $HTTP_REFERER;
$debug = 'true'; //debugger.... Leave blank to turn off debug mode
// check if referrer is from inside site (so that it only drops the cookie once)
if (preg_match("/yoursite.com/i", $url)) {
$ignore = 'yes';
} else {
$ignore = 'no';
}
// end referrer check.
// Decompile url variables to be placed into cookie
if ($url == '') $url = 'Bookmark'; //if no referrer than must be direct or bookmarked.
if($src == 'ov' & $ignore != 'yes') $url = 'Overture'; // edit to what you want to track
if($src == 'google' & $ignore != 'yes') $url = 'Google'; // edit to what you want to track
if($src == '' & $ignore != 'yes') $url = 'Natural Listing'; // edit to what you want to track
// set Cookies & Count if not linked from internally
if ($ignore != 'yes') {
if( $visitcount == "") $visitcount = 1; // Start Counter (if cookie doesn't exist start at 1)
else $visitcount++; // End Counter
