解决方案：以:private结尾的每个密钥都有一个__get()和toJSON()方法，由于_propMap是私有的，因此需要从它们获得数据。
我使用PayPal的PHP API从PayPal付款，我在付款完成后获得的数据作为这个返回

我想将其中的一部分（shipping_address就是其中之一）转换为json对象（使用json_encode/decode()，并将其存储在我的数据库中，这样在管理部分我就可以查看地址，这样我就知道在哪里发送东西了，但是，我无法将其转换为json对象，它只返回{}。我如何将这些详细信息存储在数据库中以便稍后查看？
编辑：
Json_encode代码
$db['address'] = json_encode((array) $dets->payer->payer_info->shipping_address);
var_dump(json_last_error());
$db['payerId'] = $dets->payer->payer_info->payer_id;
$db['prices'] = json_encode((array) $dets->transations[0]->amount);
var_dump(json_last_error());
$db['description'] = $dets->transations[0]->description;
$db['items'] = json_encode((array) $dets->transations[0]->item_list->items);
var_dump(json_last_error());
$db['links'] = json_encode((array) $dets->related_resources[0]->sale->links);
var_dump(json_last_error());
$db数组的输出是
Array
(
[userId] => 10
[paymentId] => PAY-4VC71851RJ180032AKKPAB3Y
[state] => approved
[address] => {"'u0000PayPal''Common''PPModel'u0000_propMap":{"line1":"1 Main Terrace","city":"Wolverhampton","state":"West Midlands","postal_code":"W12 4LQ","country_code":"GB"}}
[payerId] => P77LD9M7MUQN2
[prices] => []
[description] =>
[items] => []
[links] => []
)
所以有些正在被编码，有些正在学习。
这也困扰了我一段时间，我很难找到一个直截了当的答案。我使用的是当前的PHP REST STK，在示例ExecutePayment.PHP文件中看到了这样的内容：
// Execute the payment
// (See bootstrap.php for more on `ApiContext`)
$result = $payment->execute($execution, $apiContext);
echo "<html><body><pre>";
var_dump($result);
echo "</pre><a href='../index.html'>Back</a></body></html>";
如前所述，$result对象对导航没有太大帮助。你不能直接对对象进行编码，因为PayPal正在SDK中自己做一些疯狂的事情。如前所述，解决方案是使用PPModal类中的toJSON（）方法将该对象直接转换为JSON：
$result = $payment->execute($execution, $apiContext);
$array = $result->toJSON();
echo '<pre>';
print_r($array);
echo '</pre>';
我希望有人能更清楚一点。
我认为某些值"未编码"的问题在于某些变量引用错误。
例如，您正在尝试编码：
$dets->transations[0]->amount
然而，我认为你需要从中获得这个价值
$dets->transactions[0]['_propMap:PayPal'Common'PPModel:private']['amount']
您的大多数变量引用都有类似的问题。
