我有这个函数可以从maxoffers表中获取所有的maxoffers：
public function maxoffers($id)
{
$offers = Maxoffer::where('article_id', $id)->latest()->get(['id', 'price', 'start', 'user_id']);
return $offers;
}
我得到这个：
[{"id":121,"price":67,"start":"Sat, 23 Apr 2016 00:00:00 +0000","user_id":8},{"id":114,"price":45,"start":"Sun, 08 May 2016 00:00:00 +0000","user_id":9},{"id":113,"price":53,"start":"Sun, 24 Apr 2016 00:00:00 +0000","user_id":8},{"id":111,"price":55,"start":"Wed, 01 Jun 2016 00:00:00 +0000","user_id":11},{"id":110,"price":53,"start":"Fri, 03 Jun 2016 00:00:00 +0000","user_id":8},{"id":107,"price":53,"start":"Wed, 03 Aug 2016 00:00:00 +0000","user_id":8},{"id":106,"price":53,"start":"Mon, 01 Aug 2016 00:00:00 +0000","user_id":8},{"id":105,"price":53,"start":"Tue, 16 Aug 2016 00:00:00 +0000","user_id":8},{"id":104,"price":55,"start":"Thu, 21 Apr 2016 00:00:00 +0000","user_id":11},{"id":101,"price":57,"start":"Wed, 17 Aug 2016 00:00:00 +0000","user_id":8}]
现在我有了alse：$start="2016年4月3日星期日00:00:00"；$end='2016年9月23日星期六00:00:00'；
我如何从$开始日期到$结束日期一天一天地浏览$offers，如果当天没有添加到$offers中的日期，则添加带有数据的新对象：
{"title":,"price":100,"start":"DATE_WHICH_NOT_EXCIST INTO_OFFERS","user_id":8}
那么，我如何处理$offers，如果从$start到$end的时间段中没有日期，那么就向json添加新对象呢？
我还没有执行以下代码，但您想要的是这样的。
试试这个：
public function maxoffers($id)
{
$start_date = ;
$end_date = ;
$offers = Maxoffer::where('article_id', $id)
->where('start', '>=', $start_date)
->where('start', '<=', $end_date)
->get(['id', 'price', 'start', 'user_id']);
$start_date = 'Sun, 03 Apr 2016 00:00:00';
$end_date = 'Sat, 23 Sep 2016 00:00:00';
while (strtotime($start_date) <= strtotime($end_date)) {
$start_date = date ("Y-m-d", strtotime("+1 day", strtotime($start_date)));
$count = 0;
foreach($offers as $offer) {
if(strtotime($offer->start) == strtotime($start_date)) {
$count++;
}
}
if($count == 0) {
Maxoffer::create(['title' => null, 'price' => '100', 'start' => $start_date, 'user_id' => 8 ]);
}
}
// do some code to update $offers variable before you return it
return $offers;
}
