I assume you've fixed this by now... but here's a recursive method  
that I think does what you want:

// overrides non-numeric keys recursively
public function override($default, $page)
{
     foreach ($page as $key => $val)
     {
         if (isset($page[$key]) && $page[$key] !== "") {
             if (is_array($val)) {
                 $default[$key] = $this->override($default[$key],  
$page[$key]);
             } else {
                 if (is_numeric($key)) {
                     $default[] = $val;
                 } else {
                     $default[$key] = $val;
                 }
             }
         }
     }
     return $default;
}

Though, I wonder if it would be better to have these properties as  
class members... you may find that a bit more flexible... could even  
still have an override method to pass in an array... even offer it  
through the constructor... see below:

/* note: php4 syntax, I don't use php5 enough daily to spit it off  
the top of my head
  * but I think if you search/replace var for public and add public  
in the class definition and
  * to the functions and make singleton a static method, that should  
be most of it
