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;
