To check if a user has a specific role, you have to get a list of their roles and see if the role is listed there.
Example function:
function user_has_role($user_id, $role_name)
{
$user_meta = get_userdata($user_id);
$user_roles = $user_meta->roles;
return in_array($role_name, $user_roles);
}
Example usage:
$user_is_subscriber = user_has_role(get_current_user_id(), 'subscriber');
