php – Symfony / Doctrine Dateinterval(持续时间)如何将其存储

$reservation = new Reservation(); // Your entity object

$startDate = new DateTime('now');
$endDate = $startDate;
$endDate->modify('+'.4500.' seconds'); // Update the end time with the duration of the service

$reservation->setStartDate($startDate);
$reservation->setEndDate($endDate);

// Save the reservation
$em = $this->getDoctrine()->getManager();
$em->persist($reservation);
$em->flush();

要回答您的时区问题,最容易(我认为)是使用时间戳！在显示时,时间戳将转换为时区日期.从日期时间获取时间戳时,它是相同的,它是根据机器的时区计算的.所以时间戳在时区之间共享^^

这里的片段编辑：

// ...

// Save timestamp instead of datetime
$reservation->setStartTimestamp($startDate->getTimestamp());
$reservation->setEndTimestamp($endDate->getTimestamp());

// ...

要回答您的评论,如果您更改了持续时间,只需将持续时间保存在数据库中即可.

// First save
$reservation->setDuration(4000); // seconds

编辑持续时间时：

// Duration of a reservation change

// <- Load the $reservation to edit

$date = new DateTime();
$date->setTimestamp($reservation->getStartTimestamp()); // Got start date

$reservation->setDuration($reservation->getDuration() + 2000); // For example,duration is increased of 2000 second

$endDate = $date;
$endDate->modify('+'.$reservation->getDuration().' seconds'); // Use start date and recalculate new end date
$reservation->setEndTimestamp($endDate->getTimestamp());

// <- Then update $reservation with a persist
