Exactly the point. It's parameter polymorphism in C++/Java.

To be compatible, the only thing you have to do is adding standard
values to derived methods' parameters:
$ php -d"error_reporting=8191" -r 'class c{function f(){}} class d
extends c{function f($a){}}';
Strict Standards: Declaration of d::f() should be compatible with that
of c::f() in Command line code on line 2
$ php -d"error_reporting=8191" -r 'class c{function f(){}} class d
extends c{function f($a = null){}}';
$ [no error]
This behaviour makes sense to me.
