以小时为单位获取2个日期之间的差异，超过24小时则以秒为单位失败

Question

I have the following dates and I would like the difference in the format hh:mm:ss .

I have the following code,

$from = "2019-05-20 23:59";
$to = "2019-05-27 00:00";

$expiry_time = new DateTime($to);
$current_date = new DateTime($from);
$diff = $expiry_time->diff($current_date);
return $diff->format('%H:%I:%S');

The above returns 00:01:00 , but I expect it to be 114:01:00 , since its 6 days ( 6*24 = 114 ).

I have also tried

$from = "2019-05-20 23:59";
$to = "2019-05-27 00:00";
$time_diff = strtotime($to) - strtotime($from);
return date('H:i:s', $time_diff);

Which also gives 00:01:00

What am i missing? How can i convert this to show even beyond 24 hours? I have checked get time difference in hours minutes and seconds to no avail.

Answer 1

You can access the days property of the $diff object, and multiply it by 24 (as there are 24 hours in a day), then add the H format (to get the remaining hours) before concatenating the minutes and seconds.

The H value will never exceed 24, as the hours in a day will never be above that.

$from = "2019-05-20 23:59";
$to = "2019-05-27 00:00";

$expiry_time = new DateTime($to);
$current_date = new DateTime($from);
$diff = $expiry_time->diff($current_date);
return ($diff->days*24 + $diff->format("%H")).$diff->format(':%I:%S'); // 144:01:00
