Calculates difference between two dates in PHP
Hello All,
大家好，
In my project, I need to calculate the difference in seconds between two dates:
在我的项目中，我需要计算两个日期之间的秒差：
For Example :
例如 ：
$firstDay = "2011-05-12 18:20:20";
$secondDay = "2011-05-13 18:20:20";
Then I should get 86400 SecondsThat is 24 hours.
那么我应该得到86400 Seconds即 24 小时。
Similarly For
同样对于
$firstDay = "2011-05-13 11:59:20";
$secondDay = "2011-05-13 12:00:20";
It should return 60 Seconds.
它应该返回60 秒。
I read lots of questions in the stackoverflow But they only dealswith the difference between 2 minute fieldslike 11:50:01 and 12:10:57
我在11:50:01 和 12:10:57等2 分钟字段stackoverflow But they only deals之间阅读了很多问题

$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.
然后，您将能够使用秒来查找分钟、小时、天等。
