SoapFault异常

Question

我正在使用PHP版本5.4.16

当我进行SOAP调用时，它会给我错误：

SoapFault exception: [soap:Server] Server was unable to process request. ---> Object reference not set to an instance of an object. in /var/www/html/VAS_sms/index.php:24
Stack trace:
#0 /var/www/html/VAS_sms/index.php(24): SoapClient->__call('SendSMS', Array)
#1 /var/www/html/VAS_sms/index.php(24): SoapClient->SendSMS(Array)
#2 {main}

旁边是警告：

  

警告：具有非复合名称'SoapClient'的use语句没有   第2行的C：\ wamp \ www \ VAS_sms \ index.php中的效果

我失去了理智让它运行..

这是我的代码：

<?php
    use SoapClient;
    ini_set("soap.wsdl_cache_enabled", "0"); // disabling WSDL cache
    $wsdl_path = "https://smsvas.vlserv.com/KannelSending/service.asmx?WSDL";
    $client = new SoapClient($wsdl_path, array('trace' => 1));

    $userName = "username";
    $Password = "password";
    $SMSText = "text";
    $SMSLang = "e";
    $SMSSender = "sender";
    $SMSReceiver = "01xxxxxxxxx";

    try {
        echo "<pre>\n";
        $result = $client->SendSMS(array(
                            "Username" => $userName,
                            "Password" => $Password,
                            "SMSText" => $SMSText,
                            "SMSLang" => $SMSLang,
                            "SMSSender" => $SMSSender,
                            "SMSReceiver" => $SMSReceiver));

            function objectToArray($d){
                if (is_object($d)){
                    $d = get_object_vars($d);
                }
                if (is_array($d)){
                    return array_map(__FUNCTION__, $d);
                }
                else {return $d;}
            }

        $response_arr = objectToArray($result);
        echo "return_code= " . str_replace(";", "", $response_arr);
        echo "\n</pre>";
    }
    catch (SoapFault $exception) {
        echo $exception;      
    } 

?>

有什么建议吗？

方面问：是否有任何文件缺失我应该包含而不是use SoapClient;？！

提前致谢

在文档文件中：

<?php
use SoapClient;
$client = new SoapClient("https://smsvas.vlserv.com/KannelSending/service.asmx");
$userName = "username";
$Password = "password";
$SMSText = "text";
$SMSLang = "e";
$SMSSender = "sender";
$SMSReceiver = "01xxxxxxxxx";
$result = $client->SendSMS(array(
"Username" => $userName,
"Password" => $Password,
"SMSText" => $SMSText,
"SMSLang" => $SMSLang,
"SMSSender" => $SMSSender,
"SMSReceiver" => $SMSReceiver));
$response_arr = objectToArray($result);
echo "return_code= " . str_replace(";", "", $response_arr);
function objectToArray($d)
{
if (is_object($d))
{$d = get_object_vars($d);}
if (is_array($d))
{return array_map(__FUNCTION__, $d);}
else {return $d;}
}
?>

  

注意：我们使用PHP SoapClient来调用API Web服务，所以你   需要启用libxml PHP扩展。 因为它的反应是   对象（不是字符串）所以你需要使用它将它转换为数组   objectToArray函数。
