Weird for each loop in PHP

Question

Hate to bug you but I have the unpleasant task of sifting through another mans code to come up with fixes. Its a PHP site using a smarty template renderer. On a page is perfectly good function piece of code but for the life of me I cannot figure out how its done:

{foreach item=count from=$page}
    {foreach item=user from=$count}

Now I get the loop part but what I dont get is why the 'item' variable is not declared and where the heck the 'from' fits into the picture. I have hunted all over the web and in the PHP site manual but can find no answers. Any help would be greatly appreciated.
