Answer

Solution:

The problem is that your echoing the name in your__get() method, this will output the value straight away, but return the value of the variable to display later.

If you change the routine to...

public function __get($name){
    //echo "$name,";
    return "$name,".$this -> b[$name];
}

Your output becomes -A,b,B
