If you know the name of the extension class, you'd want to do this:

<code>
class Base {

	static function f() {
		Derived::g();
	}

	static function g() {
		print("Base\n");
	}
}

class Derived extends Base {
	static function g() {
		print("Derived\n");
	}
}

Derived::f();
</code>

If you don't know if, though, you could possibly call it as a variable.
Perhaps something like this:

<code>
class Base {

	static function f($classname) {
		$classname::g();
	}

	static function g() {
		print("Base\n");
	}
}

class Derived extends Base {
	static function g() {
		print("Derived\n");
	}
}

Derived::f('Derived');
</code>

Not sure if this is what you're looking for, but if not let us know.
