stdClass对象和foreach循环

Question

我正在使用以下代码使用Soap从网站获取数据。

$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>";

这里是输出示例：

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
                        )

                )

        )

)

如果仅返回1个结果，我可以简单地执行以下操作：

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

那么我将如何处理多个结果？

任何帮助将不胜感激。

Answer 1

这是一个数组，因此您可以使用foreach轻松地对其进行循环：

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

但是值得注意的是，默认情况下，PHP的SoapClient似乎仅在数组中包含多个值时才将数组作为PHP数组返回-如果只有一个值，您只会得到该值（不包含在其中数组）。解决此问题的一种简单方法是在SOAP_SINGLE_ELEMENT_ARRAYS构造函数中使用选项SoapClient。这将防止此行为，并确保始终获得数组。

Answer 2

我的看法是，始终确保您有一组消息，即使它是1的数组，也不会重复任何处理。

$smsMessages = is_array( $result->GetIncomingMessagesResult->SMSIncomingMessage )
    ? $result->GetIncomingMessagesResult->SMSIncomingMessage
    : array( $result->GetIncomingMessagesResult->SMSIncomingMessage );

foreach ( $smsMessages as $smsMessage )
{
    echo $smsMessage->Reference;
}

Answer 3

您需要指定您的SMSIncomingMessage数组对象键。

$result->GetIncomingMessagesResult->SMSIncomingMessage[0]->Reference;

或

foreach ($result->GetIncomingMessagesResult->SMSIncomingMessage as $message)
{
$reference = $message[0]->Reference;
//...
}

Answer 4

迭代数组？！ ：-）

foreach ($result->GetIncomingMessagesResult->SMSIncomingMessage as $message)
{
    $reference = $message->Reference;
    //...
}

Answer 5

转换对象转换数组

$array = (array) json_decode(['TEST'=>true]);
