Model方法

基本方法

查找

Model::find(1);查找第一条
Model::where('username','jacklin')->get();
Model::where('id','>','1')->get();
Model::get();
Model::all();

增加

$id = 1;$username = 'jacklin';Model::save();
$data = ['id'=>1,'username'=>'jacklin'],  Model::fill($data),Model::save();
Model::create($data);//数组

修改：

$user = Model::find(4);
$user -> username = 'jacklin2';
Model::save();
Model::where('id',$id)->update($data);//数组

删除

Model::where('id',$id)->delete();
