You can use php curl functions. Have a look at http://stackoverflow.com/questions/561816/php-curl-extract-an-xml-response — Anuruddha Lanka Liyanarachchi, Mar 08 '16 at 11:29

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 "\nSOAP Error\n".$error."\n";
            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.

Getting this error : Fatal error: Using $this when not in object context in C:\wamp\www\test\curl.php on line 4 – hemanth kumar Mar 08 '16 at 13:48
@hemanthkumar Library load must be used in some function of controller class and make sure it is extending CI_Controller. – dreams true Mar 08 '16 at 13:52
Its not in Code Igniter,. I'm just using it in flat PHP, – hemanth kumar Mar 08 '16 at 13:55
okey remove 1st line, download Nusoap library, include and use – dreams true Mar 08 '16 at 14:22
