Betreff: Re: [PHP-DEV] [RFC] Skipping parameters take 2
Hi!
Is it possible to use the default parameter on inheritance?
class Bar {
function foo($a='a', $b='b') {}
}
class Baz extends Bar {
function foo($a=default, $b=default) {
// do something
parent::foo($a, $b);
}
}
It's not part of the original proposal, and I'm not sure how easy it would be
to implement, but it sounds like a nice
extension, I didn't think about it. Since the RFC is already in vote, I won't
change it now, but I'll look into if
it's possible to do
it, and if the RFC is accepted, and it proves possible, I'll propose it
separately.

This would be quite a nice feature, even if this RFC does not pass. Just as
hint, there are ambiguous case which need to
be considered:
interface A{
function foo($a=1);
}
interface B{
function foo($a="hi");
}
class C implements A, B{
function foo($a=default){} //what would be the default value?
}
Cheers,
Robert
The default value have be the one of the parent.
if there is no parent you have the following options:
* Syntax error (I prefer)
* If defined use from interface
* If ambiguous:
* Syntax error
* Choose one (bad in my opinion)
