ThinkPhp5 模型查询结果转化成数组

          **ThinkPhp5 模型查询结果转化成数组**   

$user = USER::get(1);//此时$user是object$user = USER::get(1)->toarray();//此时$user是array 一位数字组$user = USERR::where('id',1)->select();//此时$user是二维数组，第二维是object$user = USERR::where('id',1)->select();$user = collection($user)->toarray();//此时$user就是二维数组了 collection 是thinkphp助手函数//如果$user是空，collection($user)返回空数组
