Why don't you pass a parameter in your function?

function returnArray($key=null){
  $array = array(
     0 => "kittens",
     1 => "puppies"
  );
  return is_null($key) ? $array : $array[$key];    
}

echo returnArray(0); // only 0 key
echo returnArray(); // all the array

Without testing for any errors

function returnArray($i){
  static $array = array(
             0 => "kittens",
             1 => "puppies"
         );
  return $array[$i];    
}

echo returnArray(0);

There is no way to do that without any temporary variable.

ps: it is a sample of "godlike" function. Function should not return more, than you need.
