At this page Select2 shows us how to retrieve information from an API (PHP and so on) via Ajax.
How should I send an array from PHP to match with this example?
I tried with
$response_body = json_encode($data, JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES ); $response = new Response( $response_body, 200 ); return $response;
where $data is an array (of course!).
