Bug description: Odd E_STRICT notice raised when using Interfaces
Description:
------------
When an interface is a parent of a class, the interface is implying a
specific profile for a given function (here its __get) even though it is
not defined in the interface itself. This is making it impossible to
overload and/or change the profile of the function in a descendant class.
Reproduce code:
---------------
The following will produce this notice:
Strict Standards: Declaration of Z_Concrete::__get() should be compatible
with that of Z_Abstract::__get() in xxx on line 16
<?php
error_reporting(E_ALL | E_STRICT);
interface Z_Interface
{ }
abstract class Z_Abstract implements Z_Interface
{
public function __get($name)
{
return;
}
}
class Z_Concrete extends Z_Abstract
{
public function & __get($name)
{
return null;
}
}
$t = new Z_Concrete();
This code will not produce a notice:
<?php
error_reporting(E_ALL | E_STRICT);
abstract class Z_Abstract
{
public function __get($name)
{
return;
}
}
class Z_Concrete extends Z_Abstract
{
public function & __get($name)
{
return null;
}
}
$t = new Z_Concrete();
The only difference is that the former has an interface as a parent, the
latter does not.
Expected result:
----------------
No E_STRICT notice raised
Actual result:
--------------
E_STRICT notice raised.
