Bug description: Enforcing a method without specifying the arguments
Description:
------------
The purpose of this is to allow an abstract class or an interface to
enforce the implementation of a method, without however enforcing the
arguments signature.
This is -as I understand it- not a bug, but a feature request.
Reproduce code:
---------------
/***
* This works in PHP5 but does not anymore in PHP6
*/
class Parnt {
public function foo() {}
}
class Child extends Parnt {
public function foo($arg){}
}
/***
* Those don't work in either 5 or 6
*/
abstract class Abst {
abstract public function foo();
}
class Child2 extends Abst {
public function foo($arg){}
}
interface Int {
public function foo();
}
class Child3 implements Int {
public function foo($arg){}
}
Expected result:
----------------
/***
* Proposal for a solution
*/
abstract class AbstFixed {
abstract public function foo;
}
class Child4 extends AbstFixed {
public function foo($arg){}
}
// => Declaring the method without parenthesis (which currently throws a
parse error) would allow the implementations of this method to use any
argument signature they please.
Actual result:
--------------
At the moment those three examples throw a fatal error in PHP6 with :
Declaration of Child::foo() must be compatible with that of Parnt::foo()
I don't think it is a bug, but I think having the capability to allow
variable function signatures would definitely be a plus, especially with
PHP6 coming that prevents the first example to work.
