php Password protect a page

Password protection for a single page. Visitors are required to enter a password and username into a login form to view the page content.

Code:

<?php
// Define your username and password
$username = "someuser";
$password = "somepassword";
if ($_POST['txtUsername'] != $username || $_POST['txtPassword'] != $password) {
?>
<h1>Login</h1>

<form name="form" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    <p><label for="txtUsername">Username:</label>
    <br /><input type="text" title="Enter your Username" name="txtUsername" /></p>
    <p><label for="txtpassword">Password:</label>
    <br /><input type="password" title="Enter your password" name="txtPassword" /></p>
    <p><input type="submit" name="Submit" value="Login" /></p>
</form>
<?php

}
else {

?>
<p>This is the protected page. Your private content goes here.</p>

<?php

}

?>
