How can PHP developers ensure the security of sensitive data, such as user profiles, while allowing certain users, like admins, to make changes within the application?

To ensure the security of sensitive data in PHP applications, developers can implement role-based access control (RBAC) where different users have different levels of access. This can be achieved by assigning roles to users and checking their role before allowing them to perform certain actions on sensitive data. Admin users can be granted higher levels of access to make changes within the application. 

// Check user role before allowing access to sensitive data
if($user->role == 'admin'){
    // Code to allow admin user to make changes to sensitive data
} else {
    // Code to restrict access for non-admin users
}
