How can the code snippet provided in the forum thread be improved to correctly display the "logged in" message only when a user is authenticated?

The issue with the code snippet is that it displays the "logged in" message regardless of whether the user is authenticated or not. To fix this, we need to check if the user is authenticated before displaying the message. This can be done by adding a condition that checks if the user is logged in before showing the message. 

<?php
session_start();

if(isset($_SESSION['user_id'])) {
    echo "Welcome, you are logged in!";
} else {
    echo "Please log in to view this content.";
}
?>
