Email when user changes profile

I have 2 issues:

1. My client wants to receive an email when the user updates their profile. I’m using the following code but I’m not sure where to put it. I created a plugin but I get the error message “syntax error, unexpected ‘add_filter'(T_STRING) (34,1)”

add_filter ( 'wppb_edit_profile_success', 'wppb_email_after_edit', 10, 3 );
function wppb_email_after_edit($request, $form_name, $user_id){
   // for more information about wp_get_current_user please see http://codex.ww.wp.xz.cn/Function_Reference/wp_get_current_user
   // this is useful in case you want something more then just the user_login and ID
   if ( $form_name == 'edit_profile' ){
      $user_id = get_current_user_id();
   }
 
   $user = get_user_by('id', $user_id);
   $url = admin_url("/user-edit.php?user_id=$user_id");
 
   $to = get_option( 'admin_email' );
   $subject = "User: $user->user_login succesfully edited his account.";
   $message = "<p>User: $user->user_login succesfully edited or registered his account. View his account at <a href='$url'>his account</a></p>";
   $headers = "Content-type: text/html";
 
   wp_mail($to, $subject, $message, $headers);
}

2. The user wants to know what fields the user changed. How can I capture this information in the email?

Thanks!
