PHP, Get tomorrows date from date

Use DateTime

$datetime = new DateTime('tomorrow');
echo $datetime->format('Y-m-d H:i:s');

Or:

$datetime = new DateTime('2013-01-22');
$datetime->modify('+1 day');
echo $datetime->format('Y-m-d H:i:s');

Or:

$datetime = new DateTime('2013-01-22');
$datetime->add(new DateInterval("P1D"));
echo $datetime->format('Y-m-d H:i:s');

Or in PHP 5.4+:

echo (new DateTime('2013-01-22'))->add(new DateInterval("P1D"))
                                 ->format('Y-m-d H:i:s');

 $tomorrow = date("Y-m-d", strtotime('tomorrow'));

or

  $tomorrow = date("Y-m-d", strtotime("+1 day"));
