How can server-side validation and access control be implemented to enhance the security of a PHP file editing feature?

To enhance the security of a PHP file editing feature, server-side validation can be implemented to ensure that only authorized users can access and modify files. Access control can be enforced by checking the user's credentials before allowing them to edit files. This can help prevent unauthorized access and malicious file modifications. 

// Server-side validation and access control for PHP file editing feature

session_start();

// Check if user is logged in
if (!isset($_SESSION['user_id'])) {
    // Redirect to login page if user is not logged in
    header("Location: login.php");
    exit();
}

// Check if user has permission to edit files
if ($_SESSION['role'] != 'admin') {
    // Redirect to unauthorized page if user does not have permission
    header("Location: unauthorized.php");
    exit();
}

// Code to allow file editing feature
// This code will only be executed if the user is logged in and has admin role
