//Here Key is the value of "id" attribute 
$final_output = array(
    1 => array(

      20, ////As it doesnt have any child 
      21 ////As it doesnt have any child 
     ), 
);

這裏，1：着陸頁，15：頁腳，18：存檔（它的「id」屬性）等等

上面的數組後，我將不得不做第n級循環。
喜歡：

foreach($final_output as $res) 
{ 
    if(is_array($res)) 
    { 
     //Then do something, i am not sure how this achivable 
    } 
}

是我迄今所做的，但沒有成功。

//To find out the how manhy levels are in array 
$unique_level = array_unique(array_map(function ($i) { return $i['item_level']; }, $list)); 

$parent_data = $level_data = array(); 
foreach($list as $key=>$res) 
{ 
    if($res['parent']==0) 
    { 
     if(!array_key_exists($res['id'],$parent_data)) // First insert all unique parent at level 1 
     { 
      $parent_data[$res['id']] = $res; 
     } 
    } 

    $level_data[$res['parent']][] = array(
      'display_name' => $res['display_name'], 
      'id' => $res['id'], 
      'parent' => $res['parent'], 
    ); 
}

我得最近的是...

$list = json_decode($data, true); 
$baseList = array_combine(array_column($list,'id'), $list); 
$hierarchy = []; 

foreach ($baseList as $newItem) { 
    $parent = $newItem['parent']; 
    $hierarchy[$parent][] = $newItem['id']; 
} 
function buildTree ($startNode, $hierarchy) { 
    $newLevel = []; 
    foreach ($startNode as $children) { 
     if (isset($hierarchy[$children])) { 
      $newLevel[$children] = buildTree($hierarchy[$children], $hierarchy); 
     } 
     else { 
      $newLevel[$children] = $children; 
     } 
    } 
    return $newLevel; 
} 
$finalOutput = buildTree ($hierarchy[0], $hierarchy); 
print_r($finalOutput);

你的問題是，你有相同的元素......

1 => array(
      2=>array(5=>array(9=>array(10,11))), 
      3=>array(6=>array(12=>array(13,14))), 
      4,//As it doesnt have any child 
      7,//As it doesnt have any child 
      8 //As it doesnt have any child 
    ),

正如你幾乎有元素4,7和8沒有一個鍵 - 數組中的所有元素都有一個鍵，這是行不通的。

，我所做的就是輸出...

嗨，試試這個代碼：

$results=array();

    foreach ($list as $key => $value) { 
    if($value['parent']==0) 
    { 
    $results[$value['id']]=$value; 
    $id=$value["id"]; 

    } 
    if($id==$value['parent']&&$id!="") 
    { 
    $results[$id][$value['id']]=$value; 
    $parent=$value['id']; 
    } 

    if($parent==$value['parent']&&$parent!="") 
    { 

    $results[$id][$parent][$value['id']]=$value; 
    $parent1=$value['id']; 

    } 
    if($parent1==$value['parent']&&$parent1!="") 
    { 

    $results[$id][$parent][$parent1][$value['id']]=$value; 
    $parent2=$value['id']; 
    } 

    if($parent2==$value['parent']&&$parent2!="") 
    { 

    $results[$id][$parent][$parent1][$parent2][$value['id']]=$value; 
    $parent3=$value['id']; 
    } 

    } 
    echo '<pre>'; 
    print_r($results); 
    echo '</pre>';
