#42520 [Ver]: Type hinting: function still gets called if type mismatch occurs

ID: 42520 User updated by: konstantin at boyandin dot com Reported By: konstantin at boyandin dot com Status: Verified Bug Type: Documentation problem Operating System: Windows XP PHP Version: Irrelevant New Comment: I was using the Windows binary PHP 5.2.4 distribution. Note: xdebug was installed when I found that behavior (no explicit options for it set in php.ini). I will try the situation without xdebug but with error handler set/unset.
