Edit report at https://bugs.php.net/bug.php?id=35057&edit=1 ID: 35057 Comment by: lsmith@php.net Reported by: antonsub at pochtamt dot ru Summary: abstract method inheritance and interface implementation problem Status: Not a bug Type: Bug Package: Scripting Engine problem Operating System: Linux PHP Version: 5.1.0RC4 Block user comment: N Private report: N New Comment: see #43200 Previous Comments: ------------------------------------------------------------------------ [2005-11-01 21:53:46] helly@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php B::foo is not A::foo, so when C inherits B it gets B::foo and when it implements A it gets A:foo, obviously A::foo and B::foo are different. That\'s what the error tells you. ------------------------------------------------------------------------ [2005-11-01 21:12:39] antonsub at pochtamt dot ru Description: ------------ Code given produces fatal error: Can't inherit abstract function A::foo() (previously declared abstract in B) in foo.php on line 20 Reproduce code: --------------- <?php interface A { public function foo($id); } abstract class B { abstract public function foo($id); } class C extends B { public function foo($id) { echo "foo\n"; } } class D extends C implements A {} var_dump(new D); ?> Expected result: ---------------- But is expected to run cleanly. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=35057&edit=1
