stdClass 对象和 foreach 循环 [英] stdClass object and foreach loops

问题描述

我正在使用以下代码从使用 Soap 的网站获取数据.

$client = new SoapClient('http://some.url.here');类 SMSParam {公共 $CellNumber;公共 $AccountKey;公共 $MessageCount;公共 $MessageBody;公共 $Reference;}$parameters = 新的 SMSParam;$参数 ->AccountKey = "$sms_key";$参数 ->MessageCount = "25";$Result = $client->GetIncomingMessages($parameters);echo "
";打印_r($结果);echo "</pre>";
以下是输出示例:
stdClass 对象([GetIncomingMessagesResult] =>标准类对象([SMSIncomingMessage] =>大批([0] =>标准类对象([传出消息ID] =>数据[参考] =>数据[消息编号] =>数据[电话号码] =>数据[消息] =>数据[接收日期] =>数据)[1] =>标准类对象([传出消息ID] =>数据[参考] =>数据[消息编号] =>数据[电话号码] =>数据[消息] =>数据[接收日期] =>数据)[2] =>标准类对象([传出消息ID] =>数据[参考] =>数据[消息编号] =>数据[电话号码] =>数据[消息] =>数据[接收日期] =>数据))))
如果只返回 1 个结果，我可以简单地执行以下操作:
$reference = $result->GetIncomingMessagesResult->SMSIncomingMessage->Reference;
那么我将如何处理多个结果?
任何帮助将不胜感激.
解决方案
它是一个数组，因此您可以使用 foreach 轻松地遍历它:
foreach ($result->GetIncomingMessagesResult->SMSIncomingMessage as $message) {echo $message->Reference;}
但是值得注意的是，默认情况下，PHP 的 SoapClient 似乎仅在数组中有多个值时才会将数组作为 PHP 数组返回 - 如果只有一个值，您只会得到该值(不包含在数组中).解决此问题的一个简单方法是在 SoapClient 构造函数中使用选项 SOAP_SINGLE_ELEMENT_ARRAYS；这将防止这种行为并确保您始终获得数组.
I am using the following code to get data from a website using Soap. 
$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>";
Here is a sample of the output:
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
                        )

                )

        )

)
If only 1 result is returned, I can simply do something like this:
$reference = $result->GetIncomingMessagesResult->SMSIncomingMessage->Reference;
So how would I go about working with multiple results?

Any help would be greatly appreciated.
解决方案
It is an array, so you can loop over it easily using foreach:
foreach ($result->GetIncomingMessagesResult->SMSIncomingMessage as $message) {
    echo $message->Reference;
}
However it is worth noting that PHP's SoapClient by default appears to return arrays as a PHP array only when there is more than one value in the array - if there is only one value you will just get that value (not contained within an array). An easy way around this is to  use the option SOAP_SINGLE_ELEMENT_ARRAYS in the SoapClient constructor; this will prevent this behaviour and ensure you always get arrays.
