This one is similar to what you're lookingt: http://www.regensburg-im-netz.de/artikel/addons-mods-and-plugins-for-phpld-11.html And here is another site where you can find others: http://wesece.com/phpld_mods.php/ (not working right now maybe later) And if you want to see a complete list of phpld mods, I have a great list.
I could be a bitch and charge, but when I owned Zorg Directories and actually used to add content, I wrote this - http://www.zorg-directory.com/blog/tracking-directory-submissions-in-phpld-with-google-analytics/ PM me if you need any help with it. It's really useful.
I don't think analytics can tell which one is from human being and which one is from automatic software.
The automatic software won't read the javascript analytics code - so google won't even count them as a visitor. No problem.
