日期和当前时间之间的时差？ [英] Time difference between a Date and current Time?

问题描述

假设我有一个有趣的视频网站向用户显示有趣的视频。在每个视频下方，我想根据视频的时间戳和当前时间，在5秒前，31分钟前，昨天，2天前内有一个声明。

我的时间戳格式为： 2011-10-17 07:08:00 。

我的日期不太好，但我猜测我需要找到2个日期/时间之间的差异，以秒为单位，然后决定是否在0秒之间& 60秒以秒显示，或60秒和3600秒显示分钟，或3600秒和3600x24sec，以小时显示，在3600x24sec& 3600x24x2sec显示昨天，等等...我相信我应该使用 strtotime（）但我似乎找不到目前的时间，因为我找到的那些解决方案 new date（）似乎不起作用

我该怎么做？

Btw，侧面的问题，当我插入一个MySQL时间戳列时，将$ code> 2011-10-17，7:08 PM EDT / / c $ c>转换为 2011-10-17 07:08:00 这是AM。如何将其存储在正确的AM / PM？

解决方案

您可以使用 php的日期时间函数。

  $ datetime1 = new DateTime（'2011-10-17 07:08:00'）; 
 $ datetime2 = new DateTime（）; 
 $ interval = $ datetime1-> diff（$ datetime2）; 
 echo $ interval-> format（'％R％a days'）; 
  

从这里可以使用一些if语句输出另一种格式的时差（秒，分钟，小时，月份等）取决于实际的时差！输出的格式是找到 here

Assume I have a funny video site that shows funny videos to users. Below every video, I want to have a statement that says "5 seconds ago", "31 minutes ago", "Yesterday", "2 days ago" based on a timestamp of the video and the current time.

The timestamp that I have is in the format: 2011-10-17 07:08:00.

I'm not too good with dates, but I'm guessing that I need to find the difference between the 2 date/time in seconds, then decide if its between 0sec & 60sec to display in seconds, or between 60sec & 3600sec to display in minutes, or between 3600sec & 3600x24sec to display in hours, between 3600x24sec & 3600x24x2sec to display yesterday, and so on... I believe I should be using strtotime() but I cant seem to find the current time as those solutions I found used new date() which does not seem to work!

How can I do this?

Btw, side question, when I insert 2011-10-17, 7:08PM EDT into a MySQL timestamp column, it gets converted to 2011-10-17 07:08:00 which is AM. How can I get it to be stored in the correct AM/PM?

解决方案

You can use the DateTime functions of php.

$datetime1 = new DateTime('2011-10-17 07:08:00');
$datetime2 = new DateTime();
$interval = $datetime1->diff($datetime2);
echo $interval->format('%R%a days');

From here on you can use some if-statements to output the time difference in another format (seconds, minutes, hours, month, etc.) depending on the actual time difference! The formats for the output are to find here
