php - 単一レベルの XML ファイルから多次元配列を構築する

Question

問題

私は単一の配列から新しい配列を構築しようとしてきLevel 1'sました。最上位、次にLevel 2それぞれの親Level 1's、最後にすべてLevel 3'sの親の内部 に到達する必要がありLevel 2'sます。

親が何であるかの違いを定義する方法は、配列に表示される順序です。

//Array Structure currently
Level 1
Level 2
Level 3
Level 3
Level 3
Level 2
Level 3
Level 3
Level 2

//Desired Array
Level 1
    Level 2
        Level 3
        Level 3
        Level 3
    Level 2
        Level 3
        Level 3
    Level 2

コード 現在、必要なものを取得するためにこれを行っています。

$i = 0;
$singleArray = [];
foreach ($jamie['Row'] as $value){
    $item  = 0;
    $id = $value->Cell->Data;
    $level = substr ($value->Cell[1]->Data, 6, 1);
    $name = $value->Cell[2]->Data;

    /* Start Level One */
    if($level==1){
        $singleArray[$i] = array(
            'key' => $i,
            'id'=>(string) $id,
            'level'=>$level,
            'name'=>(string)$name
        );
    };
    /* End Level One */
    /* Start Level Two */
    if($level==2){
        $reverseArray = array_reverse($singleArray);
        foreach($reverseArray as $key => $value) {
            if($value['level']==1){
                $reverseArray = $value['key'];
                break;
            }
        }

        $tempArray = array(
            'key' => $i,
            'id'=>(string) $id,
            'level'=>$level,
            'name'=>(string)$name
        );

        array_push($singleArray[$reverseArray],$tempArray);
    };
    /* ENdLevel Two */
    $i++;
}

基本的に私がやっていることは、配列を構築し、それがどのレベルに属しているかを確認してから、これまでの配列を取得して、最初のレベル 1 が見つかるまでそれを予約することです。それが配列内のどこにあるかをレベル1でグラブし、それを配列アイテムに貼り付けて、そこに新しい配列を挿入します。これは、レベル 2 からレベル 1 で機能します。そのレベル 3 では、機能することがわかりません :(
