从 php 中的 wcf 服务回显 xml 结果?

问题描述

我有一个 WCF 操作 GetColors，它返回一个颜色列表作为 GetColorsResult.我得到的结果很好，但是如何在 php 中循环遍历 GetColorsResult 并回显每个元素?

I have a WCF Operation GetColors which returns a list of colors as GetColorsResult. I am getting the result fine, but how do I loop through GetColorsResult in php and echo each element?

我在做:

<?php

header('Content-Type: text/plain');

echo "WCF Test\r\n\r\n";

// Create a new soap client based on the service's metadata (WSDL)
$client = new SoapClient('http://localhost:8181/Colors.svc?wsdl',array(
                         'login' => "test", 'password' => "test"));


 $retval = $client->GetColors();


 //Need to loop throuh $retval here

 echo $retval->GetColorsResult; //This throws error.




?>

有没有办法控制结果的名称，例如我没有指定WCF返回GetColorsResult，它在我的方法调用中附加了Result.同样，它将响应附加到 GetColors 以获取响应 (GetColorsResponse)

Is there way to control the name of the result, for example, I did not specify WCF to return GetColorsResult, it appended Result to my method call. Likewise, it appends Response to GetColors for the Response (GetColorsResponse)

执行print_r($retval)时的输出:

Output when doing print_r($retval):

stdClass Object
(
    [GetColorsResult] => stdClass Object
        (
            [Color] => Array
                (
                [0] => stdClass Object
                    (
                        [Code] => 1972
                        [Name] => RED
                    )

                [1] => stdClass Object
                    (
                        [Code] => 2003
                        [Name] => BLUE
                    )

                [2] => stdClass Object
                    (
                        [Code] => 2177
                        [Name] => GREEN
                    )
               )
          )
      )

推荐答案

关于你的 print_r 这应该给你所有的价值:

regarding to your print_r this should give you all the values:

<?php
$colorResult = $retval->GetColorsResult;
foreach($colorResult->Color as $color){
  echo $color->Code . " " . $color->Name . "<br />";
}
?>

这是你需要的吗?

如果您只是出于调试目的需要它，则应该使用 print_r.看看这里:print_r PHP 文档

If you just need it for debugging purposes, you should use print_r.Have a look here: print_r PHP Documentation
