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!
