PHP version: 5.2.10
PHP Bug Type: Class/Object related
Bug description: Interfaces not Inherited in Method Signatures
Description:
------------
In proper OOP, i should be able to define an interface, and have a class
or abstract class implement it.
If I create a class (or abstract class) which calls upon the interface
in a method signature, everything is ok.
However; if I extend the aforementioned class (or extend unto an
abstract class), and I call upon the class which implements the
interface, my compilation fails.
Even if I provide a method in my interface and implement it in the class
which uses the interface, it still fails.
I have been able to reproduce this in both php 5.2.10 and 5.2.6
(personal and work servers, respectively)
Reproduce code:
---------------
interface Validatable {};
class Form implements Validatable
{
}
abstract class Validator
{
abstract public function Validate( Validatable $v );
}
abstract class Form_Validator
extends Validator
{
public function Validate( Form $f )
{ // do something in here...
}
}
Expected result:
----------------
I should see nothing.
OR -- if i look in memory, I should see that my Form_Validator has a
Validate method in it.
Actual result:
--------------
Fatal error: Declaration of Form_Validator::Validate() must be
compatible with that of Validator::Validate() in ....
