Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

This is consistent with how the other date functions handle overflows.

I have checked the documentation and no where in it does it say anything about how overflows are handled. Including such advisments in the documentation could be usefull.

Opinion: I do understand there are other functions to check dates prior to using a function like this one. However, it seems wrong to have a calendar function which returns anything but an error(false) when given a "bogus" date as input.
