Any procedural way should be avoided. Use OOP method for date time difference:
应避免任何程序方式。使用 OOP 方法获取日期时差：
$datetime1 = new DateTime('2016-11-30 03:55:06');//start time
$datetime2 = new DateTime('2016-11-30 11:55:06');//end time
$interval = $datetime1->diff($datetime2);
echo $interval->format('%Y years %m months %d days %H hours %i minutes %s seconds');//00 years 0 months 0 days 08 hours 0 minutes 0 seconds
You can setup difference format as per your needs.
您可以根据需要设置差异格式。
%Y - use for difference in year %m - use for difference in months %d - use for difference in days %H - use for difference in hours %i - use for difference in minutes %s - use for difference in seconds
%Y - use for difference in year %m - use for difference in months %d - use for difference in days %H - use for difference in hours %i - use for difference in minutes %s - use for difference in seconds
You can remove any of above values as per your need. For example if you only are interested in hour difference and you know that difference cant be more than 24 hours then use only %H.
您可以根据需要删除上述任何值。例如，如果您只对时差感兴趣，并且您知道时差不能超过 24 小时，则仅使用%H.
If you want to have total difference in seconds then you can use:
如果你想在几秒钟内有完全的差异，那么你可以使用：
echo $difference_in_seconds = strtotime('2016-11-30 11:55:06') - strtotime('2016-11-30 03:55:06');//28800
Depends upon your need and the final format in which you want to have time difference.
取决于您的需要和您想要具有时差的最终格式。

You can convert your timestamps to unix timestamp (time in seconds) using php strtotime and then take the difference. You now have the difference in time in seconds and can convert to what you need...hours, min, days
您可以使用 php strtotime 将时间戳转换为 unix 时间戳（以秒为单位的时间），然后取差异。您现在拥有以秒为单位的时间差异，并且可以转换为您需要的时间......小时、分钟、天

ex:
前任：
$ts1 = strtotime($start);
$ts2 = strtotime($end);
$seconds_diff = $ts2 - $ts1;
$time = ($seconds_diff/3600);

The simplest answer(for me of course) is here
最简单的答案（当然对我来说）在这里
function dateDifference($date_1 , $date_2 , $differenceFormat = '%a' )
{
$datetime1 = date_create($date_1);
$datetime2 = date_create($date_2);
$interval = date_diff($datetime1, $datetime2);
return $interval->format($differenceFormat);
}
In this case date_create() function creates the DateTime object
在这种情况下 date_create() 函数创建 DateTime 对象

try this code, tested on phpfiddle.org :-
试试这个代码，在 phpfiddle.org 上测试过：-
function timestampdiff($qw,$saw)
{
$datetime1 = new DateTime("@$qw");
$datetime2 = new DateTime("@$saw");
$interval = $datetime1->diff($datetime2);
return $interval->format('%Hh %Im');
}
echo timestampdiff('1524794340', '1524803100');
