计算PHP中两个日期之间的差异

Hello All，

在我的项目中，我需要计算两个日期之间的差异：

例如：

  $ firstDay =2011-05-12 18： 20:20 
 $ secondDay =2011-05-13 18:20:20; 
  

然后我应该得到 86400秒这是24小时。

同样对于

  $ firstDay =2011-05-13 11:59:20 
 $ secondDay =2011-05-13 12:00:20; 
  

应该返回 60秒。

我在 stackoverflow中阅读了很多问题但是他们只处理与 2分钟字段之间的区别 11:50:01和12:10:57

解决方案

  $ timeFirst = strtotime（'2011-05-12 18:20:20'）; 
 $ timeSecond = strtotime（'2011-05-13 18:20:20'）; 
 $ differenceInSeconds = $ timeSecond  -  $ timeFirst; 
  

然后，您可以使用秒钟查找分钟，小时，天等。 p>

Calculates difference between two dates in PHP

Hello All,

In my project, I need to calculate the difference in seconds between two dates:

For Example :

$firstDay = "2011-05-12 18:20:20";
$secondDay = "2011-05-13 18:20:20";

Then I should get 86400 Seconds That is 24 hours.

Similarly For

$firstDay = "2011-05-13 11:59:20";
$secondDay = "2011-05-13 12:00:20";

It should return 60 Seconds.

I read lots of questions in the stackoverflow But they only deals with the difference between 2 minute fields like 11:50:01 and 12:10:57

解决方案

$timeFirst  = strtotime('2011-05-12 18:20:20');
$timeSecond = strtotime('2011-05-13 18:20:20');
$differenceInSeconds = $timeSecond - $timeFirst;

You will then be able to use the seconds to find minutes, hours, days, etc.
