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

问题描述

我使用下面的代码从使用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 $参考; 
 
} 
 $参数=新的SMSParam; 
 $参数 - > AccountKey =$ sms_key; 
 $参数 - > MessageCount =25; 
 $ Result = $ client-> GetIncomingMessages（$ parameters）; 
 echo< pre>; 
 print_r（$ Result）; 
 echo< / pre>; 
  

以下是一个输出示例：

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

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

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

）

）

）

如果只返回1个结果，我可以简单地做这样的事情： / p>

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

那么我该如何处理多个结果呢？

任何帮助将不胜感激。

解决方案

这是一个数组，所以你可以轻松地循环使用 foreach ：

  foreach（$ result-> GetIncomingMessagesResult-> SMSIncomingMessage作为$ message）{
 echo $ message->引用; 
 
 $ / code> 

不过值得注意的是PHP的 SoapClient 默认情况下，只有当数组中有多个值时，才会将数组作为一个PHP数组返回 - 如果只有一个值，您将获得该值（不包含在数组中）。一个简单的方法是在 SoapClient 构造函数中使用 SOAP_SINGLE_ELEMENT_ARRAYS 选项;这将防止这种行为，并确保你总是得到数组。

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.
