stdClass对象和foreach循环

Question

我使用以下代码从使用Soap的网站获取数据.

$client = new SoapClient('http://some.url.here');
class SMSParam {
    public $CellNumber;
    public $AccountKey;
    public $MessageCount;
    public $MessageBody;
    public $Reference;

}
$parameters = new SMSParam;
$parameters -> AccountKey = "$sms_key";
$parameters -> MessageCount = "25";
$Result = $client->GetIncomingMessages($parameters);
echo "<pre>";
print_r($Result);
echo "</pre>";

以下是输出示例:

stdClass Object
(
    [GetIncomingMessagesResult] => stdClass Object
        (
            [SMSIncomingMessage] => Array
                (
                    [0] => stdClass Object
                        (
                            [OutgoingMessageID] => data
                            [Reference] => data
                            [MessageNumber] => data
                            [PhoneNumber] => data
                            [Message] => data
                            [ReceivedDate] => data
                        )

                    [1] => stdClass Object
                        (
                            [OutgoingMessageID] => data
                            [Reference] => data
                            [MessageNumber] => data
                            [PhoneNumber] => data
                            [Message] => data
                            [ReceivedDate] => data
                        )

                    [2] => stdClass Object
                        (
                            [OutgoingMessageID] => data
                            [Reference] => data
                            [MessageNumber] => data
                            [PhoneNumber] => data
                            [Message] => data
                            [ReceivedDate] => data
                        )

                )

        )

)

如果只返回1个结果,我可以简单地做这样的事情:

$reference = $result->GetIncomingMessagesResult->SMSIncomingMessage->Reference;

那么我将如何处理多个结果呢？

任何帮助将不胜感激.

它是一个数组,因此您可以使用foreach以下方法轻松遍历它:

foreach ($result->GetIncomingMessagesResult->SMSIncomingMessage as $message) {
    echo $message->Reference;
}

但是值得注意的是,SoapClient默认情况下,只有当数组中有多个值时,PHP 才会将数组作为PHP数组返回 - 如果只有一个值,则只获得该值(不包含在数组中).解决这个一个简单的方法是使用选项SOAP_SINGLE_ELEMENT_ARRAYS在SoapClient构造函数; 这将防止此行为并确保您始终获得数组.
