php object

我正在使用某人编写的PHP类来与BaseCamp API接口。

我正在执行的特定调用是检索待办事项列表中的项目，这工作正常。

我的问题是，我不确定如何仅访问返回的对象的属性。以下是返回对象var_dump：todo-items

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)

如何访问此对象的部分？todo-items

答案 1

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

所以，是子对象。如果您可以这样设置它，那么您也可以以相同的方式阅读它：$object->{'todo-list'}

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

另一种可能性：

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

如果你想把它转换为一个数组，这可以更容易一点（即明显的访问），这段代码几乎是逐字逐句地从Zend_Config中获取的，并将为你转换。$ret['todo-list']

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;
}

答案 2

试试这个最简单的方法！

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