Um..I don't think you can do that like that...I think you need to echo it:

[code=php:0]function displayLogin(){
  global $logged_in;
  if($logged_in){
      echo "<h1>Logged In!</h1>";
      echo "Welcome <b>$_SESSION[username]</b>, you are logged in. <a href=\"logout.php\">Logout</a>";
  }
  else{
echo '<h1>Login</h1>';
echo '<form action="" method="post">';
echo '<table align="left" border="0" cellspacing="0" cellpadding="3">';
echo '<tr><td>Username:</td><td><input type="text" name="user" maxlength="30"></td></tr>';
echo '<tr><td>Password:</td><td><input type="password" name="pass" maxlength="30"></td></tr>';
echo '<tr><td colspan="2" align="left"><input type="checkbox" name="remember">';
echo '<font size="2">Remember me next time</td></tr>';
echo '<tr><td colspan="2" align="right"><input type="submit" name="sublogin" value="Login"></td></tr>';
echo '<tr><td colspan="2" align="left"><a href="register.php">Join</a></td></tr>';
echo '</table>';
echo '</form>';
  }
}[/code]

Try this:

[code]
<?

function confirmUser($username, $password){
  global $conn;
  /* Add slashes if necessary (for query) */
  if(!get_magic_quotes_gpc()) {
$username = addslashes($username);
  }

  $q = "select password from users where username = '$username'";
  $result = mysql_query($q,$conn);
  if(!$result || (mysql_numrows($result) < 1)){
      return 1; //Indicates username failure
  }


  $dbarray = mysql_fetch_array($result);
  $dbarray['password']  = stripslashes($dbarray['password']);
  $password = stripslashes($password);

  if($password == $dbarray['password']){
      return 0; //Success! Username and password confirmed
  }
  else{
      return 2; //Indicates password failure
  }
}

function checkLogin(){
  /* Check if user has been remembered */
  if(isset($_COOKIE['cookname']) && isset($_COOKIE['cookpass'])){
      $_SESSION['username'] = $_COOKIE['cookname'];
      $_SESSION['password'] = $_COOKIE['cookpass'];
  }


  if(isset($_SESSION['username']) && isset($_SESSION['password'])){
      /* Confirm that username and password are valid */
      if(confirmUser($_SESSION['username'], $_SESSION['password']) != 0){
        /* Variables are incorrect, user not logged in */
        unset($_SESSION['username']);
        unset($_SESSION['password']);
        return false;

}


function displayLogin(){

  }


  $_POST['user'] = stripslashes($_POST['user']);
