PHP SOAPClient Request Issue - php

Question

I am trying to call this web service http:// 115. 186. 182.11/csws/Service.asmx?op=SendSMS with following PHP code but it gives me exception Error mate in Script: Server was unable to process request. ---> Object reference not set to an instance of an object.
Will highly appreciate your help on this.
try {
$client = new SoapClient("http://115.186.182.11/csws/Service.asmx?wsdl");
$method = 'SendSMS';
$params = array(
new SoapParam('xxxxx', 'Src_nbr'),
new SoapParam('xxxxxx', 'Password'),
new SoapParam('xxxxx', 'Dst_nbr'),
new SoapParam('xxxxx', 'Mask'),
new SoapParam('Message is test message', 'Message')
);
$result = $client->__call($method,$params);
}
catch(SoapFault $e){
echo "Error mate in Script: " . $e->getMessage();
}
echo "<pre>";
var_dump($result);
echo "</pre>";
$xmlobj = simplexml_load_string($result);
print_r($xmlobj);
FOllowing is the specification...

I followed the below method finally and it is working perfect in production.
$fields = '<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
<soap12:Body>
<SendSMS xmlns="http://tempuri.org/">
<Src_nbr>xxxx</Src_nbr>
<Password>123</Password>
<Dst_nbr>xxxxxxxxxx</Dst_nbr>
<Mask>xxxk</Mask>
<Message>Aoa, This is Test. From xxx.</Message>
<TransactionID>11122276</TransactionID>
</SendSMS>
</soap12:Body>
</soap12:Envelope>';
echo $fields;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $postUrl);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
curl_setopt($ch, CURLOPT_POSTFIELDS, "$fields");
$response = curl_exec($ch);
curl_close ($ch);
In production the SMS API was using this code and code was exected more than 20 time per seconds and performance is good as-well.
