$date->setDate(2001, 2, 3);
echo $date->format('Y-m-d');
?>

$date->setDate(2001, 2, 29);
echo $date->format('Y-m-d') . "\n";

$date->setDate(2001, 14, 3);
echo $date->format('Y-m-d') . "\n";
?>

The above example will output:

2001-02-28
2001-03-01
2002-02-03


Be warned, DateTime::setDate() does not check for invalid input.



Illustration:

<?php

$dt = new DateTime();

$dt->setDate(2012, 11, 31); // returns DateTime object and not false although this date does not exist

echo $dt->format('Y-m-d'); // output: 2012-12-01

?>



No error was generated on entering a non existing date, php silently changed it.
