Правильно ли я провел рефакторинг сортировки на ООП?

interface Sort_methods{
function sort_s();

if(is_string($a)){
return -1;
}
 
else{
return 1;
}}
 
return $a<=>$b;
};}
 
 
 
function access_to_subarrays(){ 
foreach($this->arr as &$items){
usort($items, $this->sort_s());
}}
 
 
 
function show_result(){
 
echo implode('<br>', array_map(function($items){
 
foreach($items as $key =>$child){
if($key === 3){
$items[$key] = $items[$key] . "---";
}}
 
return implode('',$items);

$obj->show_result();
