How do I clear the page content after a form is submitted?

I currently have this code in my project: 

require_once('mysql.inc.php');
session_start();

if (!isset($_SESSION['username']) && !isset($_SESSION['uid']))
{
    login_sequence();
}
else
{
    login_check($_SESSION['username'], $_SESSION['uid']);
}

function login_sequence()
{
    echo '<p>' . $pretext . '</p><form method="post" action="" /><label for="password">Password: </label><input type="password" name="password" id="password" /><input type="submit" value="Log In" /><input type="hidden" name="submitted" /></form>';
    if (isset($_POST['submitted']))
    {
        $pword = hash('sha256', $_POST['password']);
        $query = "SELECT pword FROM users WHERE user = 'guest'";
        $result = mysql_query($query);
        $return = mysql_fetch_assoc($result);
        if ($return['pword'] == $pword)
        {
            pageout();
        }
        else
        {
            echo 'You entered the wrong password, if you are not a member, please leave.';
        }
    }
}

function login_check($username, $uid)
{
}

function pageout()
{
    echo('
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" 
    "http://www.w3.org/TR/html4/strict.dtd">

    <html lang="en-US">
        <head>
            <title></title>
            <link rel="stylesheet" type="text/css" href="" />
        </head>
        <body>
            <div id="header">
            <p>WOOT</P>
            </div>
            <div id="">
            </div>
            <div id="navigation">
            </div>
            <div id="footer">
            </div>
        </body>
    </html>
    ');
}

?>

There is a single "Guest" password stored in a database, it accesses the database and checks the password entered by the user against the one stored in the database. I want to have it so after the form is submitted and the information is correct, on the same page the form disappears and the page appears. How do I do it? How do I get rid of the form to make room for the new page?

I would make structure look slightly different:

//First
if (!isset($_POST['submitted'])) {
    //include your form only
} else {
    //Check if user submitted correct password

   //If password is correct
   if ($return['pword'] == $pword) {
       pageout();
       //OR write pageout code on different page and call header("Location: Yourpage.php");
   } else {
       //Include form or inform user about password mismatch
   }  
}

edit. Also if you use header("Location:") function make sure you're not echoing or including anything that outputs data. This will cause Headers already sent error.

at the end of your form and at the php code do this 

    if(!isset($_POST['s'])){

?>
