将日期转换为数小时 [英] Convert dates to hours

问题描述

我正在尝试第一次使用日期，我用Flash做了一些事情，但是却有所不同。

我有两个不同的日期， '我想看看他们的时间和日子的差异，我发现了太多的例子，但是我没有找到什么：

 <？php 
 $ now_date = strtotime（date（'Ymd H：i：s'））; //当前日期
 $ key_date = strtotime（date（2009-11-21 14:08:42））; 
打印日期（$ now_date  -  $ key_date）; 
 //它返回一个像5813,5814,5815等等的整数（我假定它们是秒）
？> 
  

如何将其转换为数小时或数天？

替代方法将是数学。

如何将它[秒]转换为数小时或数天？

< blockquote>

每分钟有60秒，这意味着每小时3600秒。

  $ hours = $ seconds / 3600; 
  

当然，如果你需要几天...

  $ days = $ hours / 24; 
  

I'm trying to work with dates for the first time, I did it something about that with Flash but it's different.

I have two different dates and I'd like to see the difference in hours and days with them, I've found too many examples but not what I'm loking for:

<?php
    $now_date = strtotime (date ('Y-m-d H:i:s')); // the current date 
    $key_date = strtotime (date ("2009-11-21 14:08:42"));
    print date ($now_date - $key_date);
    // it returns an integer like 5813, 5814, 5815, etc... (I presume they are seconds) 
?>

How can I convert it to hours or to days?

解决方案

Well, you can always use date_diff, but that is only for PHP 5.3.0+

The alternative would be math.

How can I convert it [seconds] to hours or to days?

There are 60 seconds per minute, which means there are 3600 seconds per hour.

$hours = $seconds/3600;

And, of course, if you need days ...

$days = $hours/24;
