PHP+；WSDL+；SOAP-如何在屏幕上显示webservice结果

我刚刚开始学习PHP，希望得到一些关于如何在数组中显示webservice结果的建议

例如，我想将货币代码从以下WSDL打印到一个数组中

$wsdl="http://www.webservicex.com/CurrencyConvertor.asmx?WSDL

到目前为止，我已经做到了这一点，但实际上什么都没有发生：

$proxyhost="proxy.cpit.ac.nz";  
$proxyport = 8080;  

$wsdl="http://www.webservicex.com/CurrencyConvertor.asmx?WSDL";

$client = new SoapClient($wsdl,
  array('proxy_host' => "$proxyhost",'proxy_port' => 8080, 'trace' => 1));

$country=array();
$result = $client->ConversionRate($country);
print_r($result);

---

基本上，它是您的$country变量

如果您查看ConversionRate Web服务，它根据需要定义FromCurrency和ToCurrency

  <s:element name="ConversionRate"> 
    <s:complexType> 
      <s:sequence> 
        <s:element minOccurs="1" maxOccurs="1" name="FromCurrency" type="tns:Currency" /> 
        <s:element minOccurs="1" maxOccurs="1" name="ToCurrency" type="tns:Currency" /> 
      </s:sequence> 
    </s:complexType> 
  </s:element> 

这应该行得通

$country = array( "FromCurrency" => "AFA",
                  "ToCurrency" => "AUD");
