如何在PHP中访问此数据的成员? [英] How to access the members of this data in PHP?

问题描述

好的.现在我放弃了.我已经玩了几个小时了.

Okay. Now I give up. I have been playing with this for hours.

• 我有一个变量名$data.

• 变量包含以下内容:(使用var_export()提取)

• I have a variable name $data.

• The variable contains these contents: (extracted by using var_export())

array (
  'headers' =>
  array (
    'content-type' => 'multipart/alternative; boundary="_689e1a7d-7a0a-442a-bd6c-a1fb1dc2993e_"',
  ),
  'ctype_parameters' => 
  array (
    'boundary' => '_689e1a7d-7a0a-442a-bd6c-a1fb1dc2993e_',
  ),
  'parts' => 
  array (
    0 => 
    stdClass::__set_state(array(
      'headers' => 
      array (
        'content-type' => 'text/plain; charset="iso-8859-1"',
        'content-transfer-encoding' => 'quoted-printable',
      ),
      'ctype_primary' => 'text',
    )),
  ),
)

我删除了一些不必要的数据.

我怎么可能访问stdClass::__set_state部分中的值?

How can I possibly access the values within the stdClass::__set_state section?

我尝试了var_export($data->parts);，但我得到的只是

I tried var_export($data->parts); but all I get is

NULL

NULL

推荐答案

该变量是声明的发布方式吗?喜欢:

Is this variable declared the way you posted it? Like:

$data = array(
          'headers' =>
             array (
             …

在这种情况下，我不太确定如何通过$data->headers访问'headers'.应该是$data['headers']，因为它是一个数组，而不是对象.

In that case, I'm not quite sure how you can access 'headers' via $data->headers. It should be $data['headers'], because it is an array, not an object.

进一步，stdClass::__set_state(array('headers' => …)) 静态调用类stdClass的方法 __set_state.我不知道该方法是什么，但只会将其返回值分配给'parts' => array(0 => ...)键.

Further down, stdClass::__set_state(array('headers' => …)) statically calls the method __set_state of the class stdClass. Whatever this method does I don't know, but only its return value will be assigned to the 'parts' => array(0 => ...) key.

如果OTOH显示的是var_dump($data)的结果，则这是不正确的废话，因为stdClass::__set_state()永远不会出现在var_dump中.在您的代码或发布的内容中，有些东西是可疑的，如果看不到更多内容，很难说.

If OTOH what you're showing is the result of var_dump($data), then this is incorrect nonsense, since stdClass::__set_state() would never show up in a var_dump. Something is fishy either in your code or in what you posted and it's hard to say without seeing more of it.

忽略以上内容，var_export以这种时髦的方式打印类.

Disregard the above, var_export prints classes this funky way.

$data['headers']应该在第一个标头部分执行此操作.再往下走，$data['parts'][0]->headers应该可以解决问题.

$data['headers'] should do it for the first headers part. Further down, $data['parts'][0]->headers should do the trick.
