Summary: signature incompatibility warning when used with
interfaces
-Status: Open
+Status: Bogus
Type: Bug
Package: Class/Object related
Operating System: all
PHP Version: 5.3.2
New Comment:
class MyClass implements A {}
new X_BASED(new MyClass);
won't be accepted while X says MyClass would be valid as a constructor
Parameter -> contract not fullfilled. So PHP's error is correct.

Description:
------------
hi, test this:
interface A {}
interface X { public function __construct(A $x); }
class A_BASED implements A {}
class X_BASED implements X { public function __construct(A_BASED $x){}
}
interface X says that the first parameter of the constructor must be
instanceof A
X_BASED implementation has a constructor with first parameter A_BASED
so, this warning is not correct:
Fatal error: Declaration of X_BASED::__construct() must be compatible
with that of X::__construct()
because
"A_BASED implements A"
