PHP：在日期范围内循环所有月份？ [英] PHP: Loop through all months in a date range?

问题描述

如果我有开始日期（例如 2009-02-01 ）和结束日期（例如 2010-01-01 ），我如何创建一个循环遍历范围内的所有日期（月）？

If I have a start date (say 2009-02-01) and an end date (say 2010-01-01), how can I create a loop to go through all the dates (months) in the range?

推荐答案

尝试

$start = $month = strtotime('2009-02-01');
$end = strtotime('2011-01-01');
while($month < $end)
{
     echo date('F Y', $month), PHP_EOL;
     $month = strtotime("+1 month", $month);
}

记住笔记 http://php.net/manual/de/datetime.formats.relative.php

相对月份值是根据他们通过的月数计算的。一个例子是+2个月2011-11-30，这将产生2012-01-30。这是由于11月份长达30天，12月份长达31天，共计61天。

Relative month values are calculated based on the length of months that they pass through. An example would be "+2 month 2011-11-30", which would produce "2012-01-30". This is due to November being 30 days in length, and December being 31 days in length, producing a total of 61 days.

从PHP5.3开始，您可以使用 http://www.php.net/manual/en/class.dateperiod.php

As of PHP5.3 you can use http://www.php.net/manual/en/class.dateperiod.php
