Not sure if it works for numeric indices, but maybe you could replace
$piece[3] with (array_key_exists(3, $piece) ? $piece[3] : ""). If you
want you could abstract that into a function, like
function array_access_element($key, $srch_array, $def=""){
return array_key_exists($key, $srch_array) ? $srch_array[$key] : $def;
}
