数据库操作


							
**数据库更新**
```
http://dfphp.dfer.site/admin/login/create_db
```
**引用模型**
```
use areasadminmodel{ConfigModel,LayoutImgModel,ArticleModel,LinkModel,MusicModel,MessageModel,NotepadModel};
```
**查询**
```

<!-- 列表 -->
 = MusicModel::select();
 = ArticleModel::order('asc')->select();
 = NotepadModel::order(['time', 'desc'])->select();
 = MusicModel::where(3)->select();
 = MusicModel::where(["id" => 3])->select();


<!-- 读取第一条数据,不满足条件则返回空 -->
 = ArticleModel::where(3)->find();
<!-- 始终读取第一条数据 -->
 = NotepadModel::where(["id" => 3])->first();

<!-- 直接生成dataTable的接口数据 -->
NotepadModel::showPage(str("admin/column/{0}_ss",[NotepadModel::getName()]));

<!-- 读取第一条数据的某个值 -->
 = ConfigModel::where(['key' => 'layout'])->value('val');


```
**新增**
```
 = ConfigModel::insert(['val'=>123]);
 = LinkModel::update();
 = LinkModel::where(null)->update();
 = LinkModel::where([])->update();
```

**修改**
```
 = LinkModel::where(3)->update();
 = ConfigModel::where(['key' => 'layout'])->update(['val'=>]);
```

**删除**
```
<!-- 根据id删除 -->
ArticleModel::where(3)->del();

<!-- 根据条件删除 -->
ArticleModel::where(['type'=>3])->del();

<!-- 清空表 -->
ArticleModel::del();

```

框架介绍


							- DfPHP
- 轻量级PHP开发框架
- [dfphp.dfer.site](http://dfphp.dfer.site)
- 由于df在做项目的过程中越来越习惯基于tp和vue的前后端分离写法，此框架将不再作为开发的首选方案，将减缓更新频率，仅作为老系统的过渡方案
