Bug description: interface from extended class conflicts with interface of
parent class
Description:
------------
when implementing interfaces that have common methods in a parent class
and an extended class, the code below produces an error. if i provide a
method in the child class, it works. it also works if the parent class
doesn't implement its' interface. but i think i should be able to inherit
from the parent class and satisfy both interfaces. though it would be easy
in this example to "code around" the problem, i ran across this in a
situation where it won't be quite as easy.
Reproduce code:
---------------
<?php
interface gotsMyMethod {
public function myMethod();
}
class theparent implements gotsMyMethod {
public function myMethod() {
return "boo!";
}
}
interface iNeedsMyMethod {
public function myMethod();
}
class child extends theparent implements iNeedsMyMethod {
}
$child = new child();
echo $child->myMethod();
?>
Expected result:
----------------
I expect the code to run without any errors and output "boo!"
Actual result:
--------------
Fatal error: Can't inherit abstract function iNeedsMyMethod::myMethod()
(previously declared abstract in gotsMyMethod) in C:\www\test\bug.php on
line 13
