如何使用DateInterval
在php中获取月间隔。
如果我选择 2015年8月5日作为开始日期而 2015年10月17日作为结束日期,那么我的数组输出应分为3个数组:
我们可以通过php DateInterval
函数来实现这个功能吗?

如果您熟悉PHP的一些有用的内置日期/时间类,这非常简单。
您可以使用DateTime
,DateInterval
和DatePeriod
来获得结果。例如:
<?php
// create start/end dates and interval
$start = new DateTime('05 Aug 2015');
$end = new DateTime('17 Oct 2015');
$interval = new DateInterval('P1D');
// DatePeriod excludes the last day
// so bump the end date by one
$end->modify('+1 day');
// create a DatePeriod for each day in range
$period = new DatePeriod($start, $interval, $end);
$months = [];
foreach ($period as $date) {
$months[$date->format('F')][] = $date->format('m/d/Y');
}
print_r($months);

请注意:您指定要将结果分成三个单独的数组。我假设结果将是动态的 - 其中月数可能会有所不同 - 所以我认为你最好生成一个多维数组的结果。
在上面的示例中,我使用月份名称作为键。 $date->format('F')
会返回full textual representation of a month, such as January or March。
如果您想获得$months
数组中包含的月份列表,您可以这样做:
print_r(array_keys($months));
返回密钥,并且应该为您提供足够的信息来访问满足您需求的数据:
Array
(
[0] => August
[1] => September
[2] => October
)
希望这会有所帮助:)
