</head>
<body>
<?php
$user=$_POST['user'];
$pass=$_POST['pass'];
// start authenticate username and password
if (($user=="") && ($pass=="")) echo " Access Granted !" ;
else echo " Access Denied!";
?>
<form action='login.php' method='post'>
<p> Username: <input type='text' name='user'> </p>
<p>Password: <input type='password' name='pass'> </p>
<input type='submit' value='Login'>
