Bug description:implementing two interfaces with same signature no longer gives
a fatal error
Description:
------------
having two different interfaces with same method no longer causes a fatal
error like in php 5.3.8. With fix for bug #43200 (my guess) it is now
possible to inherit another interface which has the same method signature
as a previous interface.
implementing an interface with methods which collide with a method name
which is already implemented by another interface should cause an error.
>From my point of OOP it does not make sense as the meaning of the colliding
interface method do not express the same, else both interfaces with the
same signature part should extend that base interface.
It's the opposite of bug #46705
Such a change of the language should not be done in a minor release.
Test script:
---------------
<?php
interface AInterface {
public function getLogicalKey();
}
interface BInterface {
public function getLogicalKey();
}
class AClass implements AInterface {
public function getLogicalKey() { return 1; }
}
class BClass extends AClass implements BInterface { }
Expected result:
----------------
Fatal error: Can't inherit abstract function BInterface::getLogicalKey()
(previously declared abstract in AInterface) in x.php on line 12
