如何计算PHP中两个日期之间的天数? [英] How to count days between two dates in PHP?

问题描述

如果我有几个字符串 $startDate 和 $endDate，它们被设置为(例如)"2011/07/01" 和 "2011/07/17"(意味着 2011 年 7 月 1 日和 2011 年 7 月 17 日).我如何计算从开始日期到结束日期的天数?在给出的示例中，它将是 17 天.

If I have a couple of strings $startDate and $endDate which are set to (for instance) "2011/07/01" and "2011/07/17" (meaning 1 July 2011 and 17 July 2011). How would I count the days from start date to end date? In the example given, it would be 17 days.

推荐答案

这是原始方法

$startTimeStamp = strtotime("2011/07/01");
$endTimeStamp = strtotime("2011/07/17");

$timeDiff = abs($endTimeStamp - $startTimeStamp);

$numberDays = $timeDiff/86400;  // 86400 seconds in one day

// and you might want to convert to integer
$numberDays = intval($numberDays);
