Я хочу рассчитать время, не проведенное между определенными часами в периоды времени.
Вы можете думать, что это калькулятор сверхурочной работы.
Входы:
//This two is work start and end time.
$starttime="22:00";
$endtime="02:00";
//This two is person's entrance and exit time.
$entrance="2016-06-24 20:00:00"$exit="2016-06-25 05:00:00"
В этом случае ответ должен быть 5 часов. (Может быть в секундах)
Время входа и выхода может быть больше (несколько дней) или короче (тот же день). И время начала, и время окончания могут быть в один и тот же день. (например: 09: 00-10: 00)
Я проверил этот вопрос, но код работает неправильно, если период времени включает полночь.
Спасибо за ваши ответы.
Вот код для вас, код, который рассчитывает время и:
Выход:
Array
(
[total_in_hours] => 5
[total_in_minutes] => 300
[days] => 1
[is_over_midnight] => 1

[total_min_middle_days] => 0
[total_min_last_day] => 180

Если вы можете получить дату и время для starttime
а также endtime
маленькая функция getTimestampDiff
будет делать то, что вам нужно.
//This two is work start and end time.
$starttime = "2016-06-24 22:00";
$endtime = "2016-06-25 02:00";
//This two is person's entrance and exit time.
$entrance = "2016-06-24 20:00:00";
$exit = "2016-06-25 05:00:00";
function getTimestampDiff($startTime, $endTime)
{
$start = new DateTime($startTime);
$end = new DateTime($endTime);
return $end->getTimestamp() - $start->getTimestamp();
}
$timeIdle = getTimestampDiff($starttime, $endtime);
$timeWorking = getTimestampDiff($entrance, $exit);
$res = ($timeWorking - $timeIdle);
echo sprintf("Time worked in minutes: %d<br />", $res / 60);
echo sprintf("Time worked in hours: %d", $res / 60 / 60);
Выход:
Time worked in minutes: 300
Time worked in hours: 5
