Correct way to add other email recipients in this handler.php


How should I add another email address to this handler.php? It is line 22. Every time I change a little thing, something else stops working. I’d like to be sure I’m doing this correctly.

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
Tested working with PHP5.4 and above (including PHP 7 )

require_once './vendor/autoload.php';

use FormGuide\Handlx\FormHandler;

$pp = new FormHandler(); 

$validator = $pp->getValidator();


$pp->sendEmailTo(''); // ← Your email here

echo $pp->process($_POST);
