如何使用连字符名访问这个对象属性?

I'm using a PHP class someone wrote to interface with the BaseCamp API.

我正在使用一个PHP类，有人编写它来与BaseCamp API进行接口。

The particular call I'm doing is to retrieve the items in a todo list, which works fine.

我正在做的一个特定的调用是检索待办事项列表中的项，它可以正常工作。

My problem is, I'm not sure how to access just the todo-items property of the object that is returned. Here's the var_dump of the returned object:

我的问题是，我不确定如何访问返回对象的todo-items属性。下面是返回对象的var_dump:

object(stdClass)[6]
  public 'completed-count' => string '0' (length=1)
  public 'description' => string 'Description String' (length=89)
  public 'id' => string '12345' (length=7)
  public 'milestone-id' => string '' (length=0)
  public 'name' => string 'Error Reports' (length=13)
  public 'position' => string '1' (length=1)
  public 'private' => string 'false' (length=5)
  public 'project-id' => string '58904' (length=7)
  public 'tracked' => string 'false' (length=5)
  public 'uncompleted-count' => string '1' (length=1)
  public 'todo-items' => 
    object(stdClass)[3]
      public 'todo-item' => 
        object(stdClass)[5]
          public 'completed' => string 'false' (length=5)
          public 'content' => string 'content string here' (length=133)
          public 'created-on' => string '2009-04-16T20:33:31Z' (length=20)
          public 'creator-id' => string '23423' (length=7)
          public 'id' => string '234' (length=8)
          public 'position' => string '1' (length=1)
          public 'responsible-party-id' => string '2844499' (length=7)
          public 'responsible-party-type' => string 'Person' (length=6)
          public 'todo-list-id' => string '234234' (length=7)
  public 'complete' => string 'false' (length=5)

How can I access the todo-items portion of this object?

<?php
$x = new StdClass();
$x->{'todo-list'} = 'fred';
var_dump($x);

So, $object->{'todo-list'} is the sub-object. If you can set it like that, then you can also read it the same way.

因此，$object->{'todo-list'}是子对象。如果你可以这样设置，那么你也可以用同样的方式来阅读。

If you wanted to convert it to an array, which can be a little more easily (ie the obvious $ret['todo-list'] accessing), this code is taken almost verbatim from Zend_Config and will convert for you.

如果您想要将它转换成一个数组，这个数组可能更容易一些(例如，显而易见的$ret['todo-list']访问)，那么这段代码几乎完全是从Zend_Config获取的，并且会为您转换。

public function toArray()
{
    $array = array();
    foreach ($this->_data as $key => $value) {
        if ($value instanceof StdClass) {
            $array[$key] = $value->toArray();
        } else {
            $array[$key] = $value;
        }
    }
    return $array;
}

Try this simplest way!

试试这个简单的方法!

$obj = $myobject->{'mydash-value'};
$objToArray = array($obj);
