Description:
------------
the date / mktime gives different dates although the parameters have the same value

Test script:
---------------
php -r "echo date('d.m.Y', mktime(0,0,0, 3,9,2010));"
> 09.03.2010
php -r "echo date('d.m.Y', mktime(0,0,0, 3, 09,2010));"
> 28.02.2010


Expected result:
----------------
php -r "echo date('d.m.Y', mktime(0,0,0, 3,9,2010));"
> 09.03.2010
php -r "echo date('d.m.Y', mktime(0,0,0, 3, 09,2010));"
> 28.02.2010


Actual result:
--------------
php -r "echo date('d.m.Y', mktime(0,0,0, 3,9,2010));"
> 09.03.2010
php -r "echo date('d.m.Y', mktime(0,0,0, 3, 09,2010));"
> 28.02.2010

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

09 starts with 0, which is the start of an octal number. Octal number 09 is invalid so turned into 0.
