# Loop while changing the name of a variable

 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. Here is an example without a loop: $reactions = array(); $response =$response->getGraphEdge(); foreach ($response as$reaction) { $reactions[] =$reaction['name'] . " - " . $reaction['type']; }$next = $fb->next($response); foreach ($next as$reaction) { $reactions[] =$reaction['name'] . " - " . $reaction['type']; }$next2 = $fb->next($next); foreach ($next2 as$reaction) { $reactions[] =$reaction['name'] . " - " . $reaction['type']; }$next3 = $fb->next($next2); foreach ($next2 as$reaction) { $reactions[] =$reaction['name'] . " - " . $reaction['type']; } print_r($reactions);

 I was over-complicating this.. I didnt account for the fact that if I keep the variable name the same it gets updated on each iteration of a loop. So this worked:  $reactions = array();$response = $response->getGraphEdge(); if ($fb->next($response) == null) { foreach ($response as $reaction) {$reactions[] = $reaction['name'] . " - " .$reaction['type']; } }else { foreach ($response as$reaction) { $reactions[] =$reaction['name'] . " - " . $reaction['type']; } while ($response = $fb->next($response)) { foreach ($response as$reaction) { $reactions[] =$reaction['name'] . " - " . $reaction['type']; } } } echo " "; print_r($reactions);                 echo "
";
