PHP Web service

I am calling ASP.NET Web service using PHP 5.3 (SoapClient)
Below is my WebService code.

<soap:Body>
<CreateCustomerOrder xmlns="(url)/">
<co>
<Auth_String>string</Auth_String>
<Ext_SystemName>string</Ext_SystemName>
<Ext_SystemReferenceNumber>string</Ext_SystemReferenceNumber>
<Cust_Num>string</Cust_Num>
<Cust_Seq>int</Cust_Seq>
<Order_Date>dateTime</Order_Date>
<Cust_PO>string</Cust_PO>
<Whse>string</Whse>
<Ship_Code>string</Ship_Code>
<Taken_By>string</Taken_By>
<Item>string</Item>
<Cust_Item>string</Cust_Item>
<Qty_Ordered>string</Qty_Ordered>
<Due_Date>dateTime</Due_Date>
<Prom_Date>dateTime</Prom_Date>
<Price>string</Price>
<Notes>string</Notes>
</co>
</CreateCustomerOrder>
</soap:Body>

Below is my PHP code:

--------------------------------
$wsdl="url"; //IDOServiceClient URL
$client=new SoapClient($wsdl);
$param=array("Auth_String"=>"test", "Ext_SystemName" => "TestingApp","Ext_SystemReferenceNumber" => "Reference Number","Cust_Num" => "1","Cust_Seq" => 10,"Order_Date" => $today,"Cust_PO" => "KKPO0016","Whse" => "MAIN","Ship_Code" => "UPS","Taken_By" => "KK","Item" => "FG-GE-0991","Cust_Item" => "KK Cust Item 908","Qty_Ordered" => "1","Due_Date" => $_ndate,"Prom_Date" => $_ndate,"Price" => "1.4","Notes" => "Testing notes");
$res = $client->CreateCustomerOrder($param);
print_r($res);
-------------------------------
My problem is parameters are not passing to web service.
Can any one help me in this

Use PHP tags please, its hard to read.

It looks like you are doing it correctly, though there are a lot of parameters, so possibly passing something in incorrectly. Are you getting a response back? Or and error message?

I am getting response like below

Result
Array
(
[CreateCustomerOrderResult] => Array
(
[Status] => Error
[Message] => Error occured while processing order
[Request_ID] => 110
)

)

Error, because of parameters are not passing to my webmethod (asp.net)

What happens if you pass nothing into the method, do you get the same error? I wonder if perhaps you are passing the parameters but something about the values is incorrect.

What about the <co>?

I changed my code like below and it's working fine...

$soapClient = new SoapClient
('http://inhyvwsyte80300/IDOService/IDOServiceClient.asmx?WSDL'); //IDOServiceClient URL

$today= date("Y-m-d");
$next = mktime(0,0,0,date("m"),date("d")+1,date("Y"));
$_ndate = date("Y-m-d", $next);

try
{
$search_query = new StdClass();
$search_query->co = new StdClass();
$search_query->co->Auth_String = "test";
$search_query->co->Ext_SystemName = "TestingApp";
$search_query->co->Ext_SystemReferenceNumber = "Reference Number";
$search_query->co->Cust_Num = "1";
$search_query->co->Cust_Seq = 10;
$search_query->co->Order_Date = $today."T14:00:00";
$search_query->co->Cust_PO = "KKPO0016";
$search_query->co->Whse = "MAIN";
$search_query->co->Ship_Code = "UPS";
$search_query->co->Taken_By = "KK";
$search_query->co->Item = "FG-GE-0991";
$search_query->co->Cust_Item = "KK Cust Item 908";
$search_query->co->Qty_Ordered = "1";
$search_query->co->Due_Date = $_ndate."T14:00:00";
$search_query->co->Prom_Date = $_ndate."T14:00:00";
$search_query->co->Price = "1.4";
$search_query->co->Notes = "Testing notes";
$info = $soapClient -> CreateCustomerOrder($search_query);

} catch (SoapFault $fault) {
echo "ERROR" .$fault;
}
