I have a class:

class test {
    function __construct() {
        print 'hello';
    }
    function func_one() {
        print 'world';
    }
}

what I would like to do is a have a class that sort of extends the test class. I say 'sort of', because the class needs to be able to run whatever function the test class is able to run, but NOT run the construct unless I ask it to. I do not want to override the construct. Anyone has any idea how to achieve this?
