php DatePeriod不会按预期返回2天 [英] php DatePeriod does not return 2 days as expected

问题描述

我试着在一段时间内得到所有的日子。无论是整天还是几个小时都没关系。我使用DatePeriod的当前代码对我来说不起作用。

示例：

  [start] => DateTime对象
（
 [date] => 2014-01-27 22:40:40 
 [timezone_type] => 1 
 [时区] => +00 ：00 
）
 
 [end] => DateTime对象
（
 [date] => 2014-01-28 17:40:40 
 [timezone_type] => 1 
 [时区] => +00 ：00 
）
 
 $ interval = new DateInterval（'P1D'）; // 1Day Interval 
 $ daterange = new DatePeriod（$ time ['start']，$ interval，$ time ['end']）; 
 
 $ return ['days'] = array（）; 
 
 foreach（$ daterange as $ date）{
 $ return ['days'] [] = $ date-> format（Y-m-d）; 
} 
  

我想获得

  [0] => 2014-01-27 
 [1] => 2014-01-28 
  

但我只收到

  [0] => 2014-01-27 
  

可以更改DatePeriod参数吗？

解决方案

DatePeriod 对象忽略上一个期间。你可以通过按你的间隔增加结束日期来解决这个问题：

  $ interval = new DateInterval P1D'）; 
 $ start-> setTime（0，0）; 
 $ end-> setTime（0，0） - > add（$ interval）; 
 $ periods = new DatePeriod（$ start，$ interval，$ end）; 
  

演示

^{更新： 00:00:00）开始和结束日期的时间部分，如果您只是通过天数循环。}

I try to get all days within a period of time. It does not matter if it is a full day or only some hours. My current code using DatePeriod does not work for me.

Example:

[start] => DateTime Object
    (
        [date] => 2014-01-27 22:40:40
        [timezone_type] => 1
        [timezone] => +00:00
    )

[end] => DateTime Object
    (
        [date] => 2014-01-28 17:40:40
        [timezone_type] => 1
        [timezone] => +00:00
    )

$interval = new DateInterval('P1D'); // 1Day Interval
$daterange = new DatePeriod($time['start'], $interval ,$time['end']);

$return['days'] = array();

foreach($daterange as $date){
    $return['days'][] = $date->format("Y-m-d");
}

I would like to get

[0] => 2014-01-27
[1] => 2014-01-28

But i only get the

[0] => 2014-01-27

Is it possible to change DatePeriod parameters or something ?

解决方案

DatePeriod object ignores last period. You can solve that by increasing end date by your interval:

$interval = new DateInterval('P1D');
$start->setTime(0, 0);
$end->setTime(0, 0)->add($interval);
$periods = new DatePeriod($start, $interval, $end);

demo

^{Updated: remove (set to 00:00:00) time parts on start and end dates, if you are only looping via days.}
