我不确定我做的是否正确:

我有很多东西,比如说624件。我想做一个循环,发送7个请求,前6个超过100个项目,最后一个超过24个。

所以我做了一些数学运算,找出我要经历多少个循环。

    // this is the total number of items
    $total = $result['total_items'];
    // if we split the total into such chunks
    $chunksize = 50;
    // we will get a rest of so many items
    $rest = $total % $chunksize;
    // so including the query for the rest, we will have to repeat the query so many times
    $queries_no = (($total-$rest)/$chunksize)+1;

上面的感觉有点笨拙。这条路对吗?

PS:之后,我可以重复查询必要的次数。

    // prep loop
    $i = 0;
    $requested = 0;
    $subscribers = [];

    while ($i <= $queries_no){
        // last item
        if($i == $queries_no){
            $chunksize = $rest;
        }
        $result = $this->monkeyApp->get('lists/'.$list_id.'/members?offset='.$requested.'&count='.$chunksize);
        $subscribers = array_merge($subscribers,$result['members']);
        $requested = $requested + $chunksize;
        $i++;
    }

$subscribers = [];

for ($count = $chunksize, $offset = 0; $offset < $total; $offset += $chunksize)
{
    if ($offset + $chunksize > $total)
    {
        $count = $total % $chunksize;
    }

    $result = $this->monkeyApp->get("lists/$list_id/members?offset=$offset&count=$count");

    $subscribers = array_merge($subscribers, $result['members']);
}
