laravel-- facade 实现CURD

路由内需配置
Route::any('test1','StudentController@test1');原生CURD写法
public function test1()
{
// 查找
// $student = DB::select('select * from student');
// 增加 $bloon = DB::insert('insert into student(`name`,`age`) VALUES(?,?)',
// ['gwz','18']
// );
// 修改 $num = DB::update('update student set `age` = ? WHERE `name` = ?',
// ['20','gwz']);
// 修改返回的是被修改的条数 echo $num;

// 删除 $num = DB::delete("delete from student WHERE id = ?",['1']);
// 返回被修改的行数 echo $num;

}
