In Phalcon when any request is generated, the user provides the manual response or the response is given by controller. Response file is generated under Phalcon\Http\Response. Http responses are usually composed by headers and body.
Example
<?php
use Phalcon\Http\Response;
// Getting a response instance
$response = new Response();
// Set status code
$response->setStatusCode(404, 'Not Found');
// Set the content of the response
$response->setContent("Sorry, the e-mail doesn't exist.");
// Send response to the client
$response->send(); Output
