When namespaces were introduced, BC was no issue, so the more correct behavior of raising an error (an Error exception as of PHP 7, respectively) was adopted. So this is expected behavior, but it seems the documentation has to be improved. ------------------------------------------------------------------------ [2015-09-03 14:59:23] bensor987 at neuf dot fr "Error Exception", not "Fatal Error". The Fatal Error happens when I don't catch the Exception, sorry for that. ------------------------------------------------------------------------ [2015-09-03 14:55:39] bensor987 at neuf dot fr Description: ------------ A Fatal Error "Undefined constant" is triggered when I use a namespace on an undefined constant, but not when I don't. Test script: --------------- <?php try { echo \UNDEF_CONSTANT; } catch (Error $e) { echo "Fatal Error NS : " . $e->getMessage(); } try { echo UNDEF_CONSTANT; } catch (Error $e) { echo "Fatal Error w/o NS : " . $e->getMessage(); } Expected result: ---------------- One of these : - UNDEF_CONSTANTUNDEF_CONSTANT - Fatal Error NS : Undefined constant 'UNDEF_CONSTANT'Fatal Error w/o NS : Undefined constant 'UNDEF_CONSTANT' Actual result: -------------- Fatal Error NS : Undefined constant 'UNDEF_CONSTANT'UNDEF_CONSTANT ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=70421&edit=1
