New Comment:
Is there someone thinking (or even working) on this issue? It is really
important if you want to use different 3rd party components which
provides interfaces you have to implement to use the components and
there exists some methods _with the same signature_ more than once. In
case of different signatures I can understand there would occur
problems because PHP does not have an method overloading possibility
yet.

FWIW, I agree; I think our interface support is pretty crappy because
of this.
I'm changing this to suspended status, because maybe one day it will
appear, it's just not possible at the moment.

I know PHP != Java, but surely this sort of stuff should be documented?
Most people will expect interfaces to work like Java interfaces or C++
"interfaces" (Pure virtual abstract methods), as many other languages
seem to follow this behaviour. As I said this is debatable as it
depends how you look at things, and likewise it is fairly easy to work
round this issue.

Description:
------------
This is debateable if this is a bug or not. Personally, I don't regard
it as a bug.
Classes that implement >1 interface that share common methods raise
fatal errors. Because of the abstract nature of interfaces, no error or
warning should be rasied.
I know PHP <> Java, but Java doesn't raise any errors, and PHP5's OO
model is very close to Java's
Reproduce code:
---------------
interface FirstInterface
{
function execute();
}
interface SecondInterface
{
function execute();
}
class MyClass implements FirstInterface, SecondInterface
{
function execute()
{
echo "Hello World";
}
}
$obj = new MyClass();
$obj->execute();
Expected result:
----------------
Hello World
Actual result:
--------------
Can't inherit abstract function SecondInterface::execute()
