IMHO, a constant is not the correct beastie in this case - if you want it to
be different depending on the implementation then it ain't a constant!
You should probably have protected static variables in the interface, and
use the implementation's constructor to set the implementation-specific
value (or override the default)
interface SetKillSwitch
{
protected static $isSet = TRUE;
protected static $notes;
protected static $date = '2010-01-22T11:23:32+0000';
}
class KilledClass implements SetKillSwitch
{
public function __construct()
{
self::$isSet = FALSE;
self::$date = '2010-01-21T09:30:00+0000';
self::$notes = "Test";
}
}

And of course, "Fatal error: Interfaces may not include member variables".
Ooops, sorry :)
I tend to end up using abstract base classes rather than interfaces for
that sort of reason...
