Question

我正在做的是，在日历上列出表格中的事件。有些活动结束时间超过24小时，因此我将日期和列表拆分为日历上的单独事件。目前我的问题是标题没有显示在json响应中（请检查响应"title":"test" "title":""）。

我需要的是基于ID 1：

"title":"test" "title":"test"

例如id 1：

表ID = 1：它的startTime是14804070619 (2016-11-29 08:11:01)，endTime是1480500661 (2016-11-30 10:11:01)。

分割ID 1后

"start":"2016-11-29T09:11:01" and "end":"2016-11-29T23:59:59" "start":"2016-11-30T00:00:00" and "end":"2016-11-30T10:11:01"

ID 1的响应

[{"title":"test","start":"2016-11-29T09:11:01","end":"2016-11-29T23:59:59","class":"bg-complete-lighter "},{"title":"","start":"2016-11-30T00:00:00","end":"2016-11-30T10:11:01","class":"bg-complete-lighter "}]

Answer 1

您应该再次添加：

$title[] = $row['title'];

在第二个while循环之后;

如果不这样做，则数组标题与上一个while循环中使用的数组endIntervals的元素数量不同...

PHP中的json响应中缺少数据
