### 模型 ***** 配置好`config/database.php`文件后 在应用中创建模型目录`application/model/` ``` <?php namespace app\model; use think\Model; class Info extends Model { } ``` 控制器中使用: ``` namespace app\home\controller; use tian\Controller; use app\model\Info; class Index extends Controller { public function index() { $id = input("id"); $info = []; if($id){ $modelInfo = new Info; $info = $modelInfo->where("id",$id)->find(); } $data = [ 'info' => $info, ]; $this->fetch("index", $data); } } ``` 也可以在公共模块目录中创建模型目录`application/common/model/` ``` <?php namespace app\common\model; use think\Model; class Info extends Model { } ``` 也可以在应用模块中创建模型目录`application/home/model/` ``` <?php namespace app\home\model; use think\Model; class Info extends Model { } ```
