Two problems.
First of all, $one in class 'b' overrides $one in class 'a'. So you end
up with two variables named $one - one in 'a' and one in 'b'.
Secondly, you don't need
$display = new a;
When you create an instance if 'b' you automatically get an instance of
'a'. 'a' is part of 'b's implementation.
