Adaptation to phpAdsNew

I serve banners to a number of sites with a very similar template. At the moment there are 9 zones being called on each page, but that will change in the future, possibly more, possibly less. What I need is a programme that will check if there is a banner serving in each zone in a page and if not create a css file that looks something like this: .Advert1 { display: none; } .Advert3 { display: none; } etc... This programme will need to run on the same server as the phpAdsNew system, as the sites which call the adverts are built in asp. I have had phpAdsNew adapted in order to call banners using 3 additional columns in the database(issueType, categoryID, and position), rather than the random code generated by the system. An example of one of the sites is: www.dataweek.co.za.
