SOAP: HTTP Bad Request

Question

I am getting below error after requesting SOAP call.

fault code: HTTP, fault string: Bad Request

Is this badly formed message?

try{
    $client = new SoapClient("http://ip_add/something.asmx?WSDL", array("trace" => true, 'exceptions' => 1));

    $params = new \SoapVar('<?xml version="1.0" encoding="utf-8"?>
                <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

                    <Remitter_Contact_No xmlns="" />
                    <Beneficiary_ZIP_Code xsi:nil="true" xmlns="" />
                    <Beneficiary_EmailID xsi:nil="true" xmlns="" />

                    <Beneficiary_Bank_Name xmlns="">PNB</Beneficiary_Bank_Name>
                    </CreditTxnMessage>
                    </RemittanceService>
                </soap:Body>
                </soap:Envelope>', XSD_ANYXML);

    $result = $client->__soapCall('RemittanceService', array($params));
    highlight_string($client->__getLastRequest());
}
catch(SoapFault $fault){
    die("SOAP Fault:<br />fault code: {$fault->faultcode}, fault string: {$fault->faultstring}");
}

I don't know what's wrong here.

The whole point of the SoapClient is to convert calls to xml; so you shouldn't be doing this manually. Try this instead:

try {
    $client = new SoapClient("http://ip_add/something.asmx?WSDL", array("trace" => true, 'exceptions' => 1));

    $result = $client->RemittanceService(array(
            'CreditTxnMessage' => array(
                    'Corporate_UID' => 66666,
                    'Mandate_Type' => 'P',
                    'MICR_No' => null,
                     /* you get the idea */
                    'Beneficiary_Contact_No' => '',
                    'Beneficiary_Bank_Name' => 'PNB'
            )
    ));

    highlight_string($client->__getLastRequest());
}
catch(SoapFault $fault){
    die("SOAP Fault:<br />fault code: {$fault->faultcode}, fault string: {$fault->faultstring}");
}

The exact format of the parameters and their names would be specified in the WSDL.
