Using FaceBook PHP SDK, when I want to get the next page of results I call something along the likes of $next = $fb->next($response). Now for the next page, I would have to call $next2 = $fb->next($next). I want to put this into a loop as obviously, I will never know beforehand how many times to execute this until I get through all the pages of results. When there are no more pages, the $fb->next() call will = null.
