问一下这种 PHP 数据对象，怎么用 PHP 去调用它的值？

[frozenway]

print_r($str)的结果如下，想调用[dot:protected]里的数据，用$rs[dot:protected]调用不了

AlibabaCloud\Client\Result\Result Object

    [request:protected] => AlibabaCloud\Client\Request\RpcRequest Object

protected

封装了，去找暴露出来的方法吧

[explon]

这是对象，不是数组！

[U7Q5tLAex2FI0o0g]

槽点非常多。楼主我看你一年前就在问 PHP 相关的问题了，也不像是新手啊，但槽点相当多

1、“想调用[dot:protected]里的数据，用$rs[dot:protected]调用不了”，假设真可以调，也不是 $rs[dot:protected] ，而是 $rs->dot
2、dot:protected，实例里是无法访问的，除非类有暴露出来，比如
public function getDot()
{
return $this->dot;
}
那么你可以用 $rs->getDot();
3、看 SDK 文档比来问快。https://github.com/aliyun/openapi-sdk-php-client/blob/c3ddbd02b3216ff428adeae0b724947cbe66820a/src/Traits/HasDataTrait.php 根据源码，照道理你不应该想要获取 dot，而是里面的数据，用法如下：
$rs->get('items'); // 结果是 [items:protected] => Array

总之我很想吐槽你

[frozenway]

@baiyi 多谢提醒，找到了

[tabris17]

利用 php 的反射，通过 ReflectionMethod::setAccessible 将属性设置成可访问

@littleylv #3
更正，楼主 17 年 11 月就在做 PHP 了（ https://v2ex.com/t/402652 ）
2 年的 PHP 经验问出这样的问题……emmmm
难怪大家都黑 PHP

[frozenway]

@littleylv 哈哈，大意了，没去看文档，```->request()->toArray();```用 toArray 方法转一下才行

[wangyzj]

面向对象没学好

[sharmy]

@wangyzj 可能是没有对象？

[netherlanddennis]

oop,学习下

[zibber]

一般会有->getter() 获取对象的方法

[index90]

protected 的，难道不是 extend 一下就可以调了吗？

单身狗真惨
