What are some potential security risks associated with using PHP to control the visibility of HTML elements?

One potential security risk associated with using PHP to control the visibility of HTML elements is the possibility of client-side manipulation. If the visibility of elements is solely controlled by PHP without proper validation and sanitization, malicious users could potentially manipulate the PHP code to gain unauthorized access to sensitive information or perform malicious actions on the website. To mitigate this risk, it is important to implement server-side validation and authentication checks to ensure that only authorized users can access or modify the visibility of HTML elements based on their permissions. 

<?php
// Check if user is authenticated and has the necessary permissions
if (isset($_SESSION['user']) && $_SESSION['user']['role'] == 'admin') {
    // Show the HTML element
    echo '<div class="admin-panel">Admin Panel Content</div>';
}
?>
