YII2の多次元配列

Question

私は自分のアプリケーションでフォルダコンセプトを作成しようとしています。
APiのjson形式でo/pを返そうとしました。 私は、フォルダ、サブフォルダとサブフォルダ内のファイルを一覧表示しようとしていますが、私はこの

{ 
    "success_msg": 1, 
    "message": "success", 
    "details": [ 
    { 
     "foldername": "Test_folder_1", 
     "subfolder": [ 
     { 
      "sub_folder_name": "Test_sub_folder_1", 

     "subfile": [ 
     { 
      "filename": "test_1.pdf" 
     }, 
     { 
      "filename": "test_2.pdf" 
     } 
     ] 
     }, 
     { 
      "sub_folder_name": "test_folder", 
"subfile": [ 
     { 
      "filename": "test_3.jpg" 
     } 
     ] 
     } 
     ] 
    } 
    ] 
} 

のようなネストされた配列にしようとしたとき、私は間違ったO/p.Let私は

ことをあなたと共有取得しています

{ 
    "success_msg": 1, 
    "message": "success", 
    "details": [ 
    { 
     "foldername": "Test_folder_1", 
     "subfolder": [ 
     { 
      "sub_folder_name": "Test_sub_folder_1" 
     }, 
     { 
      "sub_folder_name": "test_folder" 
     } 
     ], 
     "subfile": [ 
     { 
      "filename": "test_1.pdf" 
     }, 
     { 
      "filename": "test_2.pdf" 
     }, 
     { 
      "filename": "test_3.jpg" 
     } 
     ] 
    }, 
    { 
     "foldername": "sample_folder", 
     "subfolder": [], 
     "subfile": [] 
    } 
    ] 
} 

そして、これは...誰もが私はサブフォルダ配列にサブファイル配列を挿入することができる方法を教えてもらえますadvancの中
感謝

public function actionFiles() { 
    ob_start(); 
    $raw = file_get_contents("php://input"); 
    $obj = json_decode($raw); 
    \Yii::$app->response->format = \yii\web\Response::FORMAT_JSON; 
    if ($obj!=null){ 
     $user_id   = $obj->cur_user_id; 
     $user_model   = User::find()->where(['id'=>$user_id])->one(); 
     $developer_id  = $user_model->createdby; 
     $folder_model  = Folder::find()->where(['developerid'=>$developer_id,'foldertype'=>'parent'])->all(); 
     $count_folder  = count($folder_model); 
     if($count_folder > '0'){

    } else { 
     $response["success_msg"] = 3; 
     $response["message"] = "Data missing"; 
     echo json_encode($response); 
    } 
}

ifフォルダが存在する状態を更新しました。あなたのコードを更新して確認してください。

if($count_folder > '0'){ 
    $response = ['success_msg' => 1, 'message' => 'success', 'details' => []]; 

    $folder_tree = []; 
    foreach($folder_model as $folder) { 
     $folder_id       = $folder['id']; 

     $sub = []; 
     $subfolder_model = Folder::find()->where(['folderid'=>$folder_id])->all(); 
     foreach ($subfolder_model as $subfolder) { 
      $sub_folder_id    = $subfolder['id']; 

      $sub_files = []; 
      $sub_file = Files::find()->where(['folderid'=>$folder_id,'subfolderid'=>$sub_folder_id])->all(); 
      foreach ($sub_file as $file) { 
       array_push($sub_files, array('filename'=> $file['filename'])); 
      } 
      array_push($sub, array('sub_folder_name'=> $subfolder['foldername'], 'subfile'=> $sub_files));     
     } 

     array($folder_tree, array('foldername'=> $folder['foldername'], 'subfolder'=> $sub)); 
    } 
    $response['details'] = $folder_tree; 

    echo json_encode($response); 
}

配列の位置をいくつか変更してコードを更新しました。

if ($count_folder > '0') { 
       $response = ['success_msg' => 1, 'message' => 'success', 'details' => []]; 
       foreach ($folder_model as $folder) { 
        $folder_id    = $folder['id']; 
        $userdet['foldername'] = $folder['foldername']; 
        $sub     = []; 
        $subfolder_model  = Folder::find()->where(['folderid' => $folder_id])->all(); 
        foreach ($subfolder_model as $subfolder) { 
        $sub_files    = []; 
         $sub_folder_id     = $subfolder['id']; 
         $sub_name['sub_folder_name'] = $subfolder['foldername']; 
         $sub_file = Files::find()->where(['folderid' => $folder_id, 'subfolderid' => $sub_folder_id])->all(); 
          echo '<pre>';print_r($sub_file); 

         foreach ($sub_file as $file) { 
          $filename['filename']  = Yii::$app->urlManager->createAbsoluteUrl('uploads/' . $file['filename']); 
          array_push($sub_files, $filename); 
         } 
         $sub_name['subfile']   = $sub_files; 
         array_push($sub, $sub_name); 
        } 

        $userdet['subfolder'] = $sub; 
        array_push($response['details'], $userdet); 
       } 
       echo json_encode($response);
