The LightMVC Framework’s HTTP message objects are the
\Zend\Diactoros\ServerRequest and the
\Zend\Diactoros\Response objects. These are PSR-7 compliant classes and are compatible with
PSR-15 compliant middleware.
In order to get a better understanding of the
ServerRequest object, please see the
ZF documentation on server-side applications.
Response object makes it possible to add headers and provide content to the application’s final response
to the client. Here is a simple example in order to do so:
$response = new Zend\Diactoros\Response(); // Write to the response body: $response->getBody()->write("Hello"); // Multiple calls to write() append: $response->getBody()->write(" World"); // now "Hello World" // Add headers // Note: headers can be added to the response after the data has been written to the body $response = $response ->withHeader('Content-Type', 'text/plain') ->withAddedHeader('X-Custom-Header', 'example');

Response object, please see the
