我想基于类别，子类别和子类别的同级来创建全动态屏幕，因为我具有如下所示的数组

array(
    array( 
        'ID' => '1','Name' => 'ABC','Subcategory' => '','ParentID' => '0'
    ),array(
        'ID' => '2','Name' => 'DEF','Subcategory' => array(
            'ID' => '3','Name' => 'QFE','Subcategory' => array(
                [0] => stdClass Object(
                    [ID] => 5,[categoryname] => Main Menu,[type] => redirectLink,[redirection_link] => main menu,[position] => center,[position_from] =>,[parent_id] => 4,[sequence] => 0
                ),[1] => stdClass Object (
                    [ID] => 6,[categoryname] => In Range,[type] => screenTitle,[redirection_link] =>,[position] => right,[position_from] => 5,[sequence] => 0,),'ParentID' => '2'
        ),);

为了使这个数组我尝试了下面的功能

function select_all($con){
    $table_name ="SELECT * FROM `Category`";
    $table_name_result = mysqli_query($con,$table_name);
    $array = mysqli_fetch_all($table_name_result,MYSQLI_ASSOC);
    return $array;
}   

function buildTree(array $elements,$parentId = 0) {
    $branch = array();

    foreach ($elements as $element) {
        if ($element['parent_id'] == $parentId) {
            $children = buildTree($elements,$element['ID']);
            if ($children) {
                $element['subcategories'] = $children;
            }
            $branch[] = $element;
        }

    }

    return $branch;
}

$select_all = select_all($con);
$subcategory = buildTree($select_all);
//echo json_encode($subcategory); die();
echo json_encode(array_map("utf8_converter",$subcategory));

使用此代码，我可以得到数组上面的内容，但我想要的数组就像ID 6的位置与ID 5正确的那样，它必须制作一个对象

我已经在buildTree（）中尝试了以下代码

if ($children) {
   $element['subcategories'] = $children;
}
if ($element['position_from'] != '') {
   $sibling = buildTree($elements,$element['position_from']);
   $element['sibling'] = $sibling;
}

但它不起作用。

有人可以帮我吗
