if (isset($_POST['name'])) { $name = $_POST['name']; echo "Hello, $name!"; }
if (isset($_POST['username']) && isset($_POST['password'])) { $username = $_POST['username']; $password = $_POST['password']; // Perform login authentication here... }
use Symfony\Component\HttpFoundation\Request; $request = Request::createFromGlobals(); if ($request->getMethod() == 'POST') { $name = $request->request->get('name'); $email = $request->request->get('email'); // Perform form processing here... }In this example, the Symfony HTTP Foundation package library is used to handle the HTTP request and retrieve the POST parameters. The code first creates a new Request object and checks if the request method is POST. If it is, the values of the "name" and "email" parameters are retrieved using the request object's "get" method. This approach can provide more advanced features, such as handling files and handling XML and JSON request bodies.
