PHP 다중 레벨 트리 노드 메뉴 표시

Question

어떻게이 구조를 다중 레벨 메뉴에 표시합니까?

array 
    0 => 
    array 
     'product_category_code' => string 'bracelets' (length=9) 
     'product_category_desc' => string 'Bracelets' (length=9)

그리고 출력은 다음과 같이해야한다 :

  다음
  는 구조입니다

내가했지만 여전히 아이가

function getChildren($rows, $p = 0) { 
$r = array(); 
foreach($rows as $row) { 
    if ($row['parent_node']==$p) { 
     var_dump($p); 
     $r[$row['product_category_code']] = getChildren($rows, $row['product_category_code']); 
    } 
} 
return $r; 

감사 노드를 표시하는 것입니다!

Answer 1

배열에 카테고리를 할당했기 때문에 여전히 카테고리가 있기 때문입니다. 당신이 할 수있는 것은 인수를 참조로 전달하고 foreach 루프에서 이미 할당 된 범주에서 배열을 지울 수있는 기능을 수행하는 것입니다. 아래의 간단한 구현.

function getChildren(&$rows, $p = 0) { 
    $r = array(); 
    foreach($rows as $row_id => $row) { 
     if ($row['parent_node']==$p) { 
      $r[$row['product_category_code']] = getChildren($rows, $row['product_category_code']); 
      unset($rows[$row_id]); 
     } 
    } 
    return $r; 
}
