如何使用非法名称访问此对象属性？

我正在使用有人编写的PHP类来与BaseCamp API交互。

我正在执行的特定呼叫是在待办事项列表中检索项目，效果很好。

我的问题是，我不确定如何仅访问todo-items返回的对象的属性。这是返回对象的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)

如何访问todo-items此对象的一部分？

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

因此，$object->{'todo-list'}是子对象。如果可以这样设置，那么您也可以用相同的方式阅读它：

echo $x->{'todo-list'};

另一种可能性：

$todolist = 'todo-list';
echo $x->$todolist;

如果您想将其转换为数组，可以更轻松一些（即，显而易见的$ret['todo-list']访问），则该代码几乎逐字地从Zend_Config中获取，并将为您转换。

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;
}

试试最简单的方法！

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