Rounding a timestamp to midnight of the next day

Question

Given a timestamp, what would be the most elegant solution to round that date up to the nearest midnight of the next day?

For example 1374246685 (19/07/13 10:11:25) would be rounded to 1374296400 (20/07/13 00:00:00).

DateTime can do this nicely:-

$midnight = (new \DateTime())->setTimestamp(1374246685)->modify('tomorrow');

PHP version >= 5.4 only though.

Otherwise it would be:-

$midnight = new \DateTime();
$midnight->setTimestamp(1374246685)->modify('tomorrow')->setTime(0, 0);

Even more elegant than Pete's solution:

$tomorrowMidnight = strtotime('tomorrow');

While that is pretty elegant it's not what I was after, that will give me tomorrow's midnight rather than the midnight of the next day of the passed in timestamp. :) – James Dawson Jul 19 '13 at 15:05
Nevermind, forgot you can pass in a timestamp in the second parameter. Thanks! – James Dawson Jul 19 '13 at 15:08
