PHP-EWS SOAP 响应是一个对象 - 如何获取特定部分？

Question

我使用此代码与 PHP-EWS 在 Exchange 2010 邮箱上创建日历项目。

<?php

include ("ExchangeWebServices.php");
include ("EWS_Exception.php");
include ("EWSType.php");
include ("NTLMSoapClient.php");
include ("NTLMStream.php");
include ("NTLMStream/Exchange.php");
include ("NTLMSoapClient/Exchange.php");

$host = "email.domain.com";
$username = "asdfasdf";
$password = "123";

$ews = new ExchangeWebServices($host, $username, $password);

$request->SendMeetingInvitations = 'SendToNone';
$request->SavedItemFolderId->DistinguishedFolderId->Id = 'calendar';
$request->Items->CalendarItem->Subject = 'this is the subject of the email';
$request->Items->CalendarItem->Start = date('c', strtotime('today'));

$request->Items->CalendarItem->End = date('c',  strtotime('today + 1 day'));
$request->Items->CalendarItem->IsAllDayEvent = true;
$request->Items->CalendarItem->LegacyFreeBusyStatus = 'Free';
$request->Items->CalendarItem->Categories->String = $category;
$request->Items->CalendarItem->Body->BodyType = 'Text';
$request->Items->CalendarItem->Body->_ = $body;

$response = $ews->CreateItem($request);

print_r($response);

?>

这工作正常，输出到浏览器的响应如下：

stdClass Object ( [ResponseMessages] => stdClass Object ( [CreateItemResponseMessage] => stdClass Object ( [ResponseCode] => NoError [ResponseClass] => Success [Items] => stdClass Object ( [CalendarItem] => stdClass Object ( [ItemId] => stdClass Object ( [Id] => AAASAHJydXVza2FAc3VicmFkLmNvbQBGAAAAAACyAesJgtiMR71+s/kuiAieBwBrnLmGR6RGTakOvWxNjsbfAAAAQwN1AABrnLmGR6RGTakOvWxNjsbfAABcYtppAAA= [ChangeKey] => DwAAABYAAABrnLmGR6RGTakOvWxNjsbfAABcYx9q ) ) ) ) ) )

我想要的唯一部分是 [Id] => 后面的 128 个字符的字符串。如果我将此对象转换为字符串，我可以像这样解析该字符串：

$var = 'stdClass Object ( [ResponseMessages] => stdClass Object ( [CreateItemResponseMessage] => stdClass Object ( [ResponseCode] => NoError [ResponseClass] => Success [Items] => stdClass Object ( [CalendarItem] => stdClass Object ( [ItemId] => stdClass Object ( [Id] => AAASAHJydXVza2FAc3VicmFkLmNvbQBGAAAAAACyAesJgtiMR71+s/kuiAieBwBrnLmGR6RGTakOvWxNjsbfAAAAQwN1AABrnLmGR6RGTakOvWxNjsbfAABcYtpzAAA= [ChangeKey] => DwAAABYAAABrnLmGR6RGTakOvWxNjsbfAABcYzc4 ) ) ) ) ) )';

$regex_pattern = "/ /";

$matches = preg_split($regex_pattern,$var);

print_r($matches[36]);

但是，我很难将对象转换为字符串。另外，如果响应稍有变化，我将不会得到正确的返回值。查看对象并返回 [Id] => 之后的值的最佳方法是什么？

为什么你不能这样做：

$id = $response->ResponseMessages->CreateItemResponseMessage->Items->CalendarItem->ItemId->Id;

优点是不需要将对象转换为字符串，只需以通常的方式获取所需的内容即可。另一个优点是，即使 M$ 更改了某些内容，返回 ID 的方式也应该保持不变以实现向后兼容性，因此这将起作用。

当您编辑日历项目时，响应几乎相同，唯一的区别是响应消息类型为 UpdateItemResponseMessage
