自己已经写出来了！谢谢大家支持！ public function getData($list,$inventory_type){ $slice = array(); $newList = array(); while (!empty($list)) { $first = array_shift($list); array_push($slice, $first); if (array_sum(array_column($slice,'avg_price')) > 650) { $last = array_pop($slice); array_unshift($list, $last); $newList['inventory_type'] = $inventory_type; $newList['order_goods'][] = $slice; $slice = array(); } if (empty($list) && !empty($slice)) { $newList['inventory_type'] = $inventory_type; $newList['order_goods'][] = $slice; $slice = array(); } } return $newList; }
