laravel 输出最后执行sql 附:whereIn的使用方法

DB::enableQueryLog();
    $data = UsersMenu::select('users_menu.*')
      - join('users as a','a.id','=','users_menu.user_id')
      - where('a.id', $user_id)- get();
//    dd($data);
//    DB::connection()- enableQueryLog();
//    $data = DB::query('select * from users_menu,users where users.id = users_menu.user_id');
    dd(DB::getQueryLog());

$data = UsersMenu::select('users_menu.*')
  - join('users as a','a.id','=','users_menu.user_id')
  - whereIn('a.id', $user_id);
