## Configuration

**Environment:**
- Configuration via PHP arrays in `application/config.php`, `application/database.php`, `application/extra/*.php`
- Environment variable override via `think\Env` class (e.g., `Env::get('database.hostname', '127.0.0.1')`)
- `.env` file present for environment-specific overrides (secrets not inspected)
- Key configs: `site.php` (site settings, email SMTP), `upload.php` (file upload rules), `queue.php` (Redis connection), `addons.php` (plugin hooks/routes)

**Build:**
- `Gruntfile.js` - Build orchestration
- Build tasks: `deploy` (copy libs from node_modules to `public/assets/libs/`), `frontend:js`, `backend:js`, `frontend:css`, `backend:css` (RequireJS r.js optimization)
- Default task: `grunt` = `['deploy', 'frontend:js', 'backend:js', 'frontend:css', 'backend:css']`
- Output: `public/assets/js/require-backend.min.js`, `require-frontend.min.js`, etc.

## Platform Requirements

**Development:**
- PHP >= 7.4 with extensions: json, curl, pdo, bcmath
- MySQL database (utf8mb4 charset)
- Redis (for queue system)
- Node.js + npm (for frontend dependencies and Grunt build)
- Composer (for PHP dependencies)
- `.env` file configured with database credentials

**Production:**
- Self-hosted PHP deployment (no Docker detected)
- Apache or Nginx web server (with URL rewriting for ThinkPHP PATH_INFO)
- MySQL database with `fa_` table prefix
- Redis for queue processing (`think-queue`)
- `public/` directory as web root
- `application/admin/command/Install/install.lock` present - indicates installation completed

## Module Structure

The application uses ThinkPHP multi-module architecture:

| Module | Purpose | Location |
|--------|---------|----------|
| `admin` | Backend admin panel | `application/admin/` |
| `index` | Frontend website | `application/index/` |
| `api` | REST API endpoints | `application/api/` |
| `common` | Shared code | `application/common/` |

## Recently Added Components

- Used by `history.js` frontend to render colored number balls in lottery result tables

**Command Controller/Model** - Online CLI command management:
- Controller: `D:\code\php\amlhc\application\admin\controller\Command.php` - CRUD for CLI commands (crud/menu/min/api generation and execution)
- Model: `D:\code\php\amlhc\application\admin\model\Command.php` - Tracks command execution history with integer timestamps, status tracking
- Validate: `D:\code\php\amlhc\application\admin\validate\Command.php` - Empty validation rules

- Model: `D:\code\php\amlhc\application\admin\model\History.php` - Simple model for `fa_history` table, no timestamp fields
- Validate: `D:\code\php\amlhc\application\admin\validate\History.php` - Empty validation rules
- Frontend: `D:\code\php\amlhc\public\assets\js\backend\history.js` - Custom colored ball rendering, loads color map from Num API at `num/getColorMap`
- Index controller: `D:\code\php\amlhc\application\index\controller\Index.php` - `get_history()` scrapes `https://history.macaumarksix.com/history/macaujc2/y/2026` using Guzzle

**SQL Schema:** `D:\code\php\amlhc\sql\macaujc_history.sql` - Defines `macaujc_history` table with full lottery record fields (expect, open_code, wave, zodiac, odd_even, big_small, etc.)
