However, a notice should already be shown for the first usage of define. ------------------------------------------------------------------------ [2013-04-12 16:57:14] anon at anon dot anon Tested on PHP 5.3.5 on Windows and I just get NULL as output all four times, and then the notice. Seems normal. ------------------------------------------------------------------------ [2013-04-12 11:21:28] rstoll at tutteli dot ch Maybe the bug only exists on windows. I got the error for 5.4.7 and 5.3.5 ------------------------------------------------------------------------ [2013-04-12 04:14:04] laruence@php.net http://3v4l.org/8knru I didn't see a "hello world" outputted ------------------------------------------------------------------------ [2013-04-11 23:23:28] rstoll at tutteli dot ch Description: ------------ It is possible to redefine NULL (however, not null). No one probably does that but it should not be possible. Maybe there are more of this kind of errors. Test script: --------------- var_dump(null); // null var_dump(NULL); // null define("NULL","hello world"); var_dump(null); // null var_dump(NULL); // hello world define("null","hello world"); //Notice: Constant null already defined ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=64637&edit=1
