// Check if the form has been submitted if ($_SERVER['REQUEST_METHOD'] == 'POST') { // Retrieve the value of the form input with the name "username" $username = $_REQUEST['username']; echo "Hello, $username!"; }
// Retrieve the value of the "page" query string parameter $page = $_GET['page']; echo "You are viewing page $page";In this example, the getRequest method is used to retrieve the value of a query string parameter named "page" from a GET request. The value is then displayed in a message indicating which page is being viewed. The package library for the getRequest method will depend on the specific PHP framework or library being used. For example, in the Laravel framework, the getRequest method is part of the Illuminate\Http\Request class, while in the Symfony framework, it is part of the Symfony\Component\HttpFoundation\Request class.
