php如何调用.NET开发的webservice
接口地址是：http://pi.f3.cn/F3WebService.asmx

要调用的方法是：

SendSMS
短信发送

大家看看短信接口应该怎么写？我老是调用不成功

我先说明下我的代码：

PHP code


<?php
class SendSMSParam
{    
    public $ToUserText; 
    public $ToUserByte; 
    public $SMSContent;
    public $PlanSendTime;
    public $MSGType; 
    public $LongCode;
}

class SendSMS
{
    public $SMSParam;
    public $ECECCID;
    public $Password;
}

$userid=1234567;//接入账户
$pwd="abcdefg";//接入密码
$mobile="13800000000";//下发手机号
$content="php测试短信";
$client=new SoapClient("http://pi.f3.cn/F3WebService.asmx?WSDL");
$SMSParam = new SendSMSParam();
$SMSParam->ToUserText=$mobile;
$SMSParam->SMSContent=$content;
$SMSParam->MSGType=5;
$SendSMSinfo=new SendSMS();
$SendSMSinfo->SMSParam=$SMSParam;
$SendSMSinfo->ECECCID=$userid;
$SendSMSinfo->Password=$pwd;
print_r($SendSMSinfo);
$client->SendSMS($SendSMSinfo);
?>
