Are there any security considerations to keep in mind when implementing hidden content functionality in PHP?

When implementing hidden content functionality in PHP, it is important to consider security implications to prevent unauthorized access to the hidden content. One way to address this is by implementing user authentication and authorization checks before displaying the hidden content. 

<?php
session_start();

// Check if user is authenticated
if(isset($_SESSION['authenticated']) && $_SESSION['authenticated'] === true) {
    // Display hidden content
    echo "This is the hidden content.";
} else {
    // Redirect user to login page
    header("Location: login.php");
    exit();
}
?>
