How do I access this object property with a hyphenated name?
提问by Ian
I'm using a PHP class someone wrote to interface with the BaseCamp API.
我正在使用某人编写的 PHP 类来与 BaseCamp API 交互。
The particular call I'm doing is to retrieve the items in a todo list, which works fine.
我正在做的特定调用是检索待办事项列表中的项目，这很好用。
My problem is, I'm not sure how to access just the todo-itemsproperty 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)
How can I access the todo-itemsportion of this object?
如何访问todo-items此对象的部分？
回答by Alister Bulman
<?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.
所以， $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阅读它。
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.
如果你想把它转换成一个更容易一点的数组（即明显的 $ret['todo-list'] 访问），这段代码几乎是从 Zend_Config 中逐字提取的，并将为你转换。
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!
试试这个最简单的方法！
$obj = $myobject->{'mydash-value'};
$objToArray = array($obj);
