Response in Phalcon Protocol

The Response component in the Phalcon Protocol is responsible for sending a response to the client. The response can be sent as plain text, HTML, JSON, or any other format that the client can understand. In this tutorial, we will learn how to use the Response component in the Phalcon Protocol to send a response to the client.

Syntax

The syntax for using the Response component in the Phalcon Protocol is as follows:

$response->setContentType($contentType, $charset);
$response->setContent($content);
$response->send();

Example

Consider the following example where we want to send a simple message to the client:

use Phalcon\Http\Response;

// Instantiate new Response object
$response = new Response();

// Set response content type to plain text and charset to UTF-8
$response->setContentType('text/plain', 'UTF-8');

// Set response content to Hello, World!
$response->setContent('Hello, World!');

// Send response to the client
$response->send();

Explanation

In the example above, we first instantiate a new Response object. We then set the content type of the response to plain text and set the charset to UTF-8 using the setContentType() method. Next, we set the content of the response to "Hello, World!" using the setContent() method. Finally, we send the response to the client using the send() method.
