PHP soap Web service asmx 问题:SOAP-ERROR:编码:对象没有

我正在尝试将数据发布到 .net Web 服务，但收到错误："SOAP-ERROR：编码：对象没有'ActiveCust' 属性"。

以下是 wsdl：

<s:element name="SubmitNewCustomerToB1">
<s:complexType>
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="Context" type="tns:B1Context"/>
<s:element minOccurs="0" maxOccurs="1" name="WebsiteName" type="s:string"/>
<s:element minOccurs="0" maxOccurs="1" name="Cust" type="tns:Customer"/>
<s:element minOccurs="1" maxOccurs="1" name="ActiveCust" type="s:boolean"/>
<s:element minOccurs="0" maxOccurs="1" name="CustomerCustomAttrs" type="tns:ArrayOfCustomAttribute"/>
</s:sequence>
</s:complexType>
</s:element>
<s:element name="SubmitNewCustomerToB1Response">
<s:complexType>
<s:sequence>
<s:element minOccurs="1" maxOccurs="1" name="SubmitNewCustomerToB1Result" type="s:int"/>
</s:sequence>
</s:complexType>
</s:element>
<s:complexType name="B1Context">
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="B1DBName" type="s:string"/>
<s:element minOccurs="1" maxOccurs="1" name="B1DefaultPriceListNumber" type="s:int"/>
<s:element minOccurs="0" maxOccurs="1" name="B1UKStandardVatCode" type="s:string"/>
</s:sequence>
</s:complexType>
<s:complexType name="Customer">
<s:complexContent mixed="false">
<s:extension base="tns:EntityObject">
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="CardCode" type="s:string"/>
<s:element minOccurs="0" maxOccurs="1" name="WebPassword" type="s:string"/>
<s:element minOccurs="0" maxOccurs="1" name="EmailAddress" type="s:string"/>
<s:element minOccurs="0" maxOccurs="1" name="Title" type="s:string"/>
<s:element minOccurs="0" maxOccurs="1" name="FirstName" type="s:string"/>
<s:element minOccurs="0" maxOccurs="1" name="Surname" type="s:string"/>
<s:element minOccurs="0" maxOccurs="1" name="Telephone" type="s:string"/>
<s:element minOccurs="0" maxOccurs="1" name="WebID" type="s:string"/>

<s:element minOccurs="0" maxOccurs="1" name="FaxNumber" type="s:string"/>
<s:element minOccurs="0" maxOccurs="1" name="Telephone2" type="s:string"/>
<s:element minOccurs="0" maxOccurs="1" name="Organisation" type="s:string"/>
<s:element minOccurs="0" maxOccurs="1" name="MobilePhone" type="s:string"/>
</s:sequence>
</s:extension>
</s:complexContent>
</s:complexType>
<s:complexType name="CustomAttribute">
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="FieldName" type="s:string"/>
<s:element minOccurs="0" maxOccurs="1" name="FieldValue" type="s:string"/>
</s:sequence>
</s:complexType>

这是我的代码：

error_reporting(E_ALL);
$Context =array(
        "B1DBName" => "Test",
        "B1DefaultPriceListNumber" => 1,
        "B1UKStandardVatCode" => "O1",
    );
$WebsiteName =array(
    "WebsiteName"=> "Tes webiste"
);
$Cust =array(
    "CardCode" => "",
    "WebPassword" => "",
    "EmailAddress" => "l@l.com",
    "Title" => "Mr",
    "FirstName" => "Luca",
    "Surname" => "Luchino",
    "Telephone" => "02094388",
    "WebID" => "1988",
    "VATNumber" => "",
    "FaxNumber" => "0209998",
    "Telephone2" => "",
    "Organisation" => "",
    "MobilePhone" => ""
);

$ActiveCust =array(
    "ActiveCust" => true
);
$CustomerCustomAttrs=array(
    $CustomAttribute=array(
        "FieldName" => "",
        "FieldValue" => ""
    )
);
//Associative array
$params = array(
    $Context,
    $WebsiteName,
    $Cust,
    $ActiveCust,
    $CustomerCustomAttrs
);
//var_dump($params);
try {
    $client = new SoapClient("http://my.asmx?wsdl");
    $result = $client->SubmitNewCustomerToB1($params);
    var_dump($result);
} 
catch (Exception $e) 
{
    echo "Error!<br />";
    echo $e -> getMessage ();
}

我得到的错误：SOAP-ERROR：编码：对象没有"ActiveCust"属性

有人可以帮助我吗？非常感谢！卢卡
