ID: 44043 User updated by: j dot boggiano at seld dot be Reported By: j dot boggiano at seld dot be Status: Open Bug Type: Class/Object related Operating System: * PHP Version: 6CVS-2008-02-04 (snap) New Comment:
As I understand it, the following example would work, right ? interface Foo { function bar(...); } class Baz implements Foo { function bar($first, $second, $third, $whatever) {} } If so, it's exactly what I'm looking for, your syntax is as good as mine as far as I'm concerned. In fact it's even better as it allows for a partial signature enforcement while still leaving the argument list "opened". Previous Comments: ------------------------------------------------------------------------ [2008-02-04 20:27:32] [EMAIL PROTECTED] What we could do is adding '...'. That way you can do stuff like: interface Foo { function bar($first, ...); } Now all classes that derive from Foo must implement the same function protocol, for instance: class Baz { function bar($first, ...) {} } Anything else would violate the inheritance rules. ------------------------------------------------------------------------ [2008-02-04 18:44:46] j dot boggiano at seld dot be Description: ------------ The purpose of this is to allow an abstract class or an interface to enforce the implementation of a method, without however enforcing the arguments signature. This is -as I understand it- not a bug, but a feature request. Reproduce code: --------------- /*** * This works in PHP5 but does not anymore in PHP6 */ class Parnt { public function foo() {} } class Child extends Parnt { public function foo($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. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44043&edit=1
