Adding Minutes to Date Time in PHP

In PHP, adding minutes to a datetime is a straightforward task. However, it may require a specific approach depending on the datetime format.

As mentioned in the inquiry, the given datetime format is "year-month-day hour:minute", e.g., "2011-11-17 05:05". To modify this datetime by adding minutes:

可以使用 DateTime 类和 DateInterval 类：

$minutes_to_add = 5;

$time = new DateTime('2011-11-17 05:05');
$time->add(new DateInterval('PT' . $minutes_to_add . 'M'));

$stamp = $time->format('Y-m-d H:i');

In this code:

1. $minutes_to_add represents the number of minutes to increment.
2. $time is created as a DateTime object from the given string.
3. $time->add() method is used with a DateInterval object to specify the modification.
4. DateInterval('PT' . $minutes_to_add . 'M') creates an interval representing the specified minutes.
5. $time is updated with the modified datetime.
6. $stamp formats the modified datetime and stores it in the desired "year-month-day hour:minute" format.

The ISO 8601 standard is utilized for duration representation, where "P{y}Y{m1}M{d}DT{h}H{m2}M{s}S" denotes a duration of {y} years, {m1} months, {d} days, and so on.

For instance, "P1Y2DT5S" corresponds to 1 year, 2 days, and 5 seconds.

In the provided example, "PT" signifies a time interval, followed by "5M", which represents adding 5 minutes.
