PHP code :

<?php
class client{
    public function __construct() {
        $param = array("location" => "https://119.73.253.101:9514/emcdsvc/",
            "uri" => "urn://119.73.253.101:9514/emcdsvc/",
            "trace" => 1);
        $this->instance = new SoapClient(NULL,$param);

        $auth_param = new stdClass();
        $auth_param->username = "env_solution";
        $auth_param->password = "Password1";

        $header_param = new SoapVar($auth_param, SOAP_ENC_OBJECT);

        $header = new SoapHeader("soap", "authenticate", $header_param, FALSE);

        $this->instance->__setSoapHeaders(array($header));

        try {
            $date_array = array("date" => date("dd-mm-yyyy"));
            $result = $this->instance->__soapCall("RealTimePriceDataWebService", $date_array);;
            print_r($result);

        } catch (Exception $e) {
            echo $e->getMessage();
        }
    }
}
$client = new client;
