Storing items in a session array as the page loads

[eluser]mattpointblank[/eluser]
Thanks for that, worked fine with a couple of changes. I had to unset the entire 'ad_array' userdata at the end of page execution (I added a function in my footer) otherwise it counts ads loaded across the entire session, not just a single page, meaning after a couple of page impressions, all the ads disappear. Thanks!
