#28712 [Com]: NULL can't be passed to argument with class type hint.

ID: 28712 Comment by: imprestavel at gameguru dot com dot br Reported By: davojan at mail dot ru Status: Open Bug Type: Zend Engine 2 problem Operating System: FreeBSD 4.7-RELEASE PHP Version: PHP5-RC3 New Comment: or just drop the type-hint unless you use your class as if it was NULL (do nothing with it), you are going to check that argument anyway keep it simple maybe it doesnt make much difference, but since php team already discussed it, probably with a similar example in mind, and went this way, i think we would need to give them a much better reason to change back Previous Comments: ------------------------------------------------------------------------ [2004-06-09 19:19:21] davojan at mail dot ru The compromise can be to add new configuration parameter, something like "allow_type_hinted_pass_null", to enable or disable this feature. ------------------------------------------------------------------------ [2004-06-09 19:02:58] davojan at mail dot ru Description: ------------ Actually it was tested in RC3 (I don't find it in PHP version list). It's very inconveniently, if I can't pass NULL instead of object to the function. In the example below the default value is used, but there is a same behaviour, when I pass NULL explicitly. I understand, that the report: http://bugs.php.net/bug.php?id=26780&edit=2 intersects with my, but my opinion is that not accepting NULLs is an evident bug, very serious bug! And my example with the default value illustrates it very well. Reproduce code: --------------- <? class foo {}; function bar (foo $f = NULL) { echo 'ok'; } bar(); ?> Expected result: ---------------- ok Actual result: -------------- Fatal error: Argument 1 must not be null in /usr/local/www/data-dist/ils/admin/test/null.php on line 3 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28712&edit=1
