根据开始时间和持续时间计算结束时间？ [英] How do you calculate an end time based on start time and duration?

问题描述

我正在建立一个活动日历，并将开始时间传递给PHP，格式为2009-09-25 15:00:00。持续时间也可以通过，格式为60分钟或3小时。从小时转为分钟不是问题。您如何将一段时间添加到已建立的起始点以正确格式化结束时间？

I'm building a event calendar and pass a start time to PHP, in the format of 2009-09-25 15:00:00. A duration gets passed as well, that might be in the format of 60 minutes or 3 hours. Converting from hours to minutes isn't the problem. How do you add a length of time to an established starting point to correctly format the end time?

推荐答案

使用 strtotime（），您可以将当前时间（2009-09-25 15:00:00）转换为时间戳，然后添加（60 * 60 * 3 = 3hrs）到时间戳。最后只需将其转换回您想要的任何时间。

Using strtotime() you can convert the current time (2009-09-25 15:00:00) to a timestamp and then add (60 * 60 * 3 = 3hrs) to the timestamp. Finally just convert it back to whatever time you want.

//Start date
$date = '2009-09-25 15:00:00';
//plus time
$plus = 60 * 60 * 3;
//Add them
$time = strtotime($date) + $plus;
//Print out new time in whatever format you want
print date("F j, Y, g:i a", $time);
