Login echo array

[Hydrian]

I have this in my website using it in my chat. I recommend it if you have a login system. and need to see if a user is or isnt logged in

PHP Code:

<?php
session_start();
include_once"config.php";
if(!isset($_SESSION['username']) || !isset($_SESSION['password'])){
         echo '<h4>You are not logged in. Please do so <a href="http://jays.netne.net/loginsystem/login.php">Login</a></h4>'; }


        else {
            echo "<h4>You are logged in </h4>";
        }
?>

The problem with this though is you will echo out text before any DOCTYPE in your HTML because a session_start() needs to be called be any headers. It might be better to just setup a string with the message and then print it out later in the body of your HTML.
