I haven't used the script in this thread at all to use phpAdsNew. I've set it up as if phpadsnew were residing on a separate computer all together and simply called it using the invocation code generated in phpAdsNew for each publication location. This works fine and i'm using it on several sites.
http://www.bostonlove.org uses it for several spots on the site include the top the middle and the bottom.
http://www.yyzlifestyle.com uses it for the stuff at the bottom.
I've tied it into the vbaffiliates hack so that it counts each link in the affiliates module each time someone clicks on the appropriate affiliate's banner - all of this with just using phpadsnew without customisation for vbulletin.
I'm even using it to track who clicks on my paypal donation buttons.
