So I thought this should be easy, but, I'm n00bing out here and failing epicly (as they say on teh interwebz).

So here's my code:

function xy() {
  $array['var1'] = x;
  $array['var2'] = y;
  echo $this->_z;
}

function _z($array) {
  $xy = $x.$y;
  return $xy;
}

So, why doesn't that seemingly simple code work? I know with views you can pass arrays and the variables are accessible in the views with just their array title, but, why doesn't it work in this case?
