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 - NOTHING stops you from passing NULL to functions. - Typhints are a shortcut for an 'instanceof' test. - now try NULL instanceof stdclass: php-cvs $ php -r 'var_dump(NULL instanceof stdclass);' bool(false) - what you probably want is function bla($x) { if (is_null($x)) { // handle null } else if ($x instanceof whatever) { // handle instance } else { // handle error } } - if you look again you'll see that you are doing *three different* things in your code. Typehints have a different usage! Previous Comments: ------------------------------------------------------------------------ [2004-06-17 05:48:33] nospam0 at malkusch dot de Description: ------------ Since RC3 I can't define optional parameters when I'm using type hinting. Why is it no more allowed to use NULL. Im used to do so from other OO Languages. So if I have to live with no NULL and want to use class Type hints, how can I use optional Paramters? Reproduce code: --------------- class Test { public function test(Test $optinalTest = null) { } } Expected result: ---------------- No Error, or a possibility to use class type hints *and* optinal parameters. Perfect would be the old behavoir, that I'm allowed to use NULL. Actual result: -------------- Fatal error: Argument 1 must not be null ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28814&edit=1
