Bug #51791 [Bgs->Opn]: constant() failed to check undefined constant and php interpreter stoped

Edit report at http://bugs.php.net/bug.php?id=51791&edit=1 ID: 51791 Updated by: philip@php.net Reported by: iliavlad at mail dot ru Summary: constant() failed to check undefined constant and php interpreter stoped -Status: Bogus +Status: Open Type: Bug Package: Reproducible crash Operating System: Windows, Linux PHP Version: 5.3.2 New Comment: I don't see this change mentioned at any of the following locations: - http://php.net/php5news - http://php.net/migration53 - http://php.net/function.constant Therefore, it can't be completely bogus. Please explain if this BC break in 5_3 is intentional. constant('IDONOTEXIST') still returns NULL however, with E_WARNING instead of E_FATAL. Previous Comments: ------------------------------------------------------------------------ [2010-05-13 00:09:29] iliavlad at mail dot ru Hi Mike, according to manual http://php.net/manual/en/function.constant.php constant() eturns the value of the constant, or NULL if the constant is not defined. And this happens with php 5.2 version. With php 5.3 there is a fatal error and php interpreter stops. There are no words about fatal error in manual. ------------------------------------------------------------------------ [2010-05-12 08:16:15] mike@php.net Thank you for taking the time to write to us, but this is not a bug.
