PHP中两个日期的总和 [英] Sum of two dates in PHP

问题描述

我怎么可以对两个日期求和？

how I can sum two dates?

我有两个这样的日期jh：i：s，我想对它们进行求和

I have two date in this format j h:i:s and I will like to sum them

我找到了这个脚本，但是没有几天的参考资料，我对此很陌生，这里是脚本，也许有人可以进行必要的更改。

I found this script but no reference about days and I'm new to this, here is the script, maybe somebody can make the necessary changes.

<?php

echo sum_the_time('01:45:22', '17:27:03');  // this will give you a result: 19:12:25

function sum_the_time($time1, $time2) {
  $times = array($time1, $time2);
  $seconds = 0;
  foreach ($times as $time)
  {
    list($hour,$minute,$second) = explode(':', $time);
    $seconds += $hour*3600;
    $seconds += $minute*60;
    $seconds += $second;
  }
  $hours = floor($seconds/3600);
  $seconds -= $hours*3600;
  $minutes  = floor($seconds/60);
  $seconds -= $minutes*60;
  return "{$hours}:{$minutes}:{$seconds}";
}

?>

用法：

我所需要的是将两个任务的两个日期相加，例如：
任务1将花费1天10小时20分钟10秒
任务2将花费3天17小时35分钟40秒

All that I need is to sum two dates from two task like: Task 1 will take 1 day 10 hour 20 mins 10 sec Task 2 will take 3 days 17 hours 35 mins 40 sec

所以结果将是任务1和任务2之间的总时间

so the result will be the total time between task 1 and two

推荐答案

只需使用strtotime并对时间戳求和，然后使用日期函数再次转换为日期：

just convert the dates using strtotime and sum the timestamps, than convert to the date again using date function:

$tmstamp = strtotime($date1) + strtotime($date2);
echo date("Y m d", $tmstamp) ;

但是为什么要首先添加两个日期？

but why would you add two dates in the first place?
