DateTime::__set_state
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.
