### 标准模块目录结构示例 (PHP)

Source: https://context7_llms

展示了一个权限模块（modules/Permissions）的标准目录组织结构。该结构清晰地划分了数据库、异常、中间件、服务提供者、路由、HTTP层（控制器、请求）以及模型等文件，有助于代码的组织和维护。

```php
├─permissions
│  ├─database          # 数据库相关文件
│  │  ├─migrations     # 数据库迁移文件
│  │  └─seeders        # 数据填充文件
│  ├─Exceptions        # 模块专用异常类
│  ├─Middlewares       # 模块中间件
│  ├─Providers         # 服务提供者
│  ├─routes            # 模块路由定义
│  ├─HTTP              # HTTP层业务逻辑
│  │  ├─Controllers    # 控制器类
│  │  └─Requests       # 表单验证请求类
│  └─Models            # 数据模型类
├─Installer.php        # 模块安装器
```

### XditnAdmin Configuration Settings in PHP

Source: https://context7_llms

This PHP configuration file defines various settings for the XditnAdmin system. It includes configurations for super administrator identification, request handling permissions, module management (including root directory, namespace, default modules, and directory structures), response handling (middleware and listeners), database logging, authentication models and guards, routing (prefix and middleware), frontend view paths, system API logging, image processing drivers and options, and backend cache key prefixes. These settings allow for fine-grained control over the XditnAdmin environment.

```php
