Date validity can be checked with a custom class.

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.
