    Another simplified example slip :) ?
    You probably know that global variables are not accessible unless
    explicitly specified, like:

    function & getX() {
       global $arr;
       return $arr[0];
    }

    Anyway, probaly not the problem in your real code, since global is not
    used within classes.
    Are you sure the code in your search method doesn't make a copy of the
    object somewhere?
