Will do. Right now I'm trying to figure out how to override a variable
set in the parent class.

Err...until I remember to put parent::__construct() in B. :)

Interesting. The parent isn't multi-generational, far as I can see. That
is, if C extends B which extends A, parent::__construct() in C does not
have access to stuff constructed in A.
I can make it work by making C extend A, but need to google a way to
inherit further up the chain.
Thanks!

As Jeff said you have to call it explicitly
class Trooper extends Person
{
public function _construct($parms)
{
parent::_construct();
//Whatever else is here
}
}

I think you're looking for parent::__construct();
The child's __construct() will replace the parent's. So if you
want to run the parent's you have to call it explicitly.

Okay, OOP newbie time again. In line 11 I declare an array.
Per IRC conversations a day or so ago, line 49 has to go into
the __construct function. However, the hope is that line 83
would add to what was done in line 49. It seems not to.
I think because the extends doesn't actually call the
__construct. Is my understanding correct? How would I achieve
the goal of adding line 83 so that $roles included 'troop' and
'nco' for an object of class NCO?
Thanks!
