In https://www.domain.com/login.php simply put at the top:

  if (isset($_POST['submit'])){
    $username = $_POST['username'];
    $password = $_POST['password'];
    //validate username and passowrd here
    $_SESSION['username'] = $username;
    $_SESSION['password'] = $password;

I believe that rajccs wants their page to perform a login to another page, then maintain the logged-in session for that other page. Not to allow other to login to their page.

Change your form action form

Below is sample dologin.php

Assume that remote host's login page accept 'username' and 'passwd' as input data
if (isset($_POST['username'])){
// create new curl session
$sessions = curl_init();

$uri = 'https://www.domain.com/login.php'; //your URL here
$postData = array('username' => $_POST['username'], 'passwd' => $_POST['passwd']); //login data stored in array format. eg: array("name" => "test", "pwd" => "test")

// set options for logging in and store cookie
curl_setopt($sessions, CURLOPT_URL, $uri);
curl_setopt($sessions, CURLOPT_POST, 1);
curl_setopt($sessions, CURLOPT_POSTFIELDS, $postData);
curl_setopt($sessions, CURLOPT_COOKIEJAR, dirname(__FILE__).'/cookie.txt');
curl_setopt($sessions, CURLOPT_FOLLOWLOCATION, 1); //auto redirect after logged in
curl_setopt($sessions, CURLOPT_HEADER, 1);
curl_setopt($sessions, CURLOPT_RETURNTRANSFER, 1);

//do logging in
