Are there any security concerns associated with allowing users to view but not edit specific fields, such as names, in a PHP-based web application?

One security concern associated with allowing users to view but not edit specific fields in a PHP-based web application is the potential for data leakage. If sensitive information, such as names, is displayed to users who should not have access to it, it could lead to privacy breaches. To mitigate this risk, you can implement access control measures to restrict which users can view certain fields. 

<?php
session_start();

// Check if user is logged in and has appropriate permissions
if(isset($_SESSION['user_id']) && $_SESSION['role'] == 'admin') {
    // Display the name field
    echo $user['name'];
} else {
    // Display a message indicating the user does not have permission to view the field
    echo "You do not have permission to view this field.";
}
?>
