找不到类'DateInterval'

问题描述

我想获取不包括最后日期的两个日期之间的日期，以下代码将用于查找日期。但是它触发了一个错误：

I want to get the date between two dates excluding last date, following code i will used to find dates. But it trigger an error saying:

代码：

$start = new DateTime('2014-08-06');
$end = new DateTime('2014-09-06');
$oneday = new DateInterval("P1D");

$days = array();
$data = "7.5";

foreach(new DatePeriod($start, $oneday, $end->add($oneday)) as $day) {
    $day_num = $day->format("N");

    if($day_num < 6) {
        $days[$day->format("Y-m-d")] = $data;
    }
}

print_r($days);

推荐答案

看起来您的php版本没有 DateInterval 类。这是一个替代方案，使用 strtotime（）：

Looks like your version of php doesn't have the DateInterval class. Here is an alternative using strtotime():

$start = '2014-08-06';
$end = '2014-09-06';

$num_days = floor((strtotime($end)-strtotime($start))/(60*60*24));
$data = '7.5';

$days = array();

for ($i=0; $i<$num_days; $i++)
    if (date('N', strtotime($start . "+ $i days")) < 6)
        $days[date('Y-m-d', strtotime($start . "+ $i days"))] = $data;

print_r($days);

结果：

Array
(
    [2014-08-06] => 7.5
    [2014-08-07] => 7.5
    [2014-08-08] => 7.5
    [2014-08-11] => 7.5
    [2014-08-12] => 7.5
    [2014-08-13] => 7.5
    [2014-08-14] => 7.5
    [2014-08-15] => 7.5
    [2014-08-18] => 7.5
    [2014-08-19] => 7.5
    [2014-08-20] => 7.5
    [2014-08-21] => 7.5
    [2014-08-22] => 7.5
    [2014-08-25] => 7.5
    [2014-08-26] => 7.5
    [2014-08-27] => 7.5
    [2014-08-28] => 7.5
    [2014-08-29] => 7.5
    [2014-09-01] => 7.5
    [2014-09-02] => 7.5
    [2014-09-03] => 7.5
    [2014-09-04] => 7.5
    [2014-09-05] => 7.5
)
