Test script: --------------- <?php trait ATrait { function bar() { $this->foo(); } abstract function foo(); } class Base { function foo() { } } class Child extends Base { use ATrait; } Actual result: -------------- PHP Fatal error: Cannot make non abstract method Base::foo() abstract in class Child in /home/jared/Temp/trait.php on line 21 Fatal error: Cannot make non abstract method Base::foo() abstract in class Child in /home/jared/Temp/trait.php on line 21 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55355&edit=1
