You can use nusoap library to use SOAP with PHP. Here is an example how you can use it. It is just similar to your query.

        $this->load->library("lib_nusoap");
        $wsdl = "https://transact-prelive.litle.com/vap/communicator/online";
        $client = new nusoap_client($wsdl, 'wsdl');

        //$client->setCredentials($api_username,$api_password);
        $error = $client->getError();
        if ($error)
        {
            echo "
SOAP Error
".$error."
";
            return false;
        }
        else
        {
            $params = array ('user' => "u82917418420715660 ", 'Password' => "dENteSXnXwfqKHF "); 
            $result = $client->call('retrive', $params);
            if ($client->fault)
            {
                print_r($result);
                print $client->fault;
            }
            else
            {
                $result_arr = json_decode($result, true);
            }    
        }
        print_r($result_arr);

Nusoap library will handle CURL API call.
