$response = Response::getInstance(); $response->setHeader('Content-Type', 'text/html'); $response->setHeader('Cache-Control', 'no-store');
$data = array('name' => 'John', 'age' => 30); $response = Response::getInstance(); $response->setHeader('Content-Type', 'application/json'); $response->setBody(json_encode($data)); $response->send();This code creates a response instance and sets the Content-Type header to indicate that the response contains JSON data. The code then encodes an array as JSON and sets it as the response body. Finally, the code sends the response to the client. Based on these examples, it is likely that Response::getInstance is part of a package or library used for web application development in PHP.
