상위 슬러그를 가져 오는 계층 구조 트리

Question

Array 
(
    [1] => Array 
     (
      [id] => 1 
      [parent_id] => 0 
      [name] => Men 
      [slug] => men 
      [status] => 1 
     ) 

    [2] => Array 
     (
      [id] => 2 
      [parent_id] => 1 
      [name] => Shoes 
      [slug] => shoes 
      [status] => 1 
     ) 


    [3] => Array 
     (
      [id] => 3 
      [parent_id] => 2 
      [name] => Sports 
      [slug] => sports 
      [status] => 1 
     )   
) 

여기 내 사이드 ​​바 메뉴 트리를 만드는 기능입니다.

function ouTree($array, $currentParent, $currentLevel = 0, $previousLevel = -1) 
{ 
    foreach ($array as $categoryId => $category) 
    { 
     if ($currentParent == $category['parent_id']) 
     { 
      if ($currentLevel > $previousLevel) echo "<ul>"; 
      if ($currentLevel == $previousLevel) echo "</li>"; 
      echo "<li><a href='/category/{$category['slug']}' title='{$category['name']}'>{$category['name']}</a>"; 
      if ($currentLevel > $previousLevel) 
       $previousLevel = $currentLevel; 
      $currentLevel++; 
      ouTree ($array, $categoryId, $currentLevel, $previousLevel); 
      $currentLevel--; 
     } 
    } 
    if ($currentLevel == $previousLevel) echo "</li></ul>"; 
} 

ouTree($array, 0); 

현재 함수는 현재 슬러그 <a href="/category/men">Men</a> 만 호출합니다. 상위 슬러그를 현재 목록 순서로 검색하거나 반복하려면 어떻게합니까? 그래서이

<a href="/category/men">Men</a> 
<a href="/category/men/shoes">Shoes</a> 
<a href="/category/men/shoes/sports">Sports</a>

OK처럼 될 것이다, 여기에 내가 몇 분 있었다뿐만이었다로 치아를 싱크하는 스크립트입니다. 의견을보세요! 그것은 스크립트의 모든 것을 설명합니다. 솔직히 말하면, 배열 구조를 복사 했으므로 곧바로 작동해야하지만 읽으면 이해할 수 있습니다. 맹목적으로 복사하여 붙여 넣기 만하면 안됩니다. 그런 식으로는 배우지 못할 것입니다 (정상적으로 작동하지 않을 것입니다. 코드,하지만 설명하기가 어렵습니다).
