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

<?php
  if (isset($_POST['submit'])){
    session_start();
    $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
action="https://www.domain.com/login.php"
to
action="dologin.php"

Below is sample dologin.php

Assume that remote host's login page accept 'username' and 'passwd' as input data
<?php

if (isset($_POST['username'])){

// create new curl session

$sessions = curl_init();



//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



curl_exec($sessions);

}
