It's probably a Bad Road you are on, but you could also consider the
dirt-simple:
function ClassName($x, $y = NULL, $z = NULL) {
if (is_null($y) && is_null($z) && is_array($x)){
foreach($x as $k => $v){
$this->$k = $v;
}
}
}
You may even be able to wrap that up in some fancy OOP thingie that
makes you happy.
