use Symfony\Component\HttpFoundation\Request; $request = new Request(); $request->setMethod('POST');
use Symfony\Component\HttpFoundation\Request; public function handleFormSubmission(Request $request) { if ($request->isMethod('POST')) { $formData = $request->request->all(); // Process form data } }In this example, we are using the $request object to check if the request method is POST and then getting all the form data submitted through the request. Therefore, the package library used in the examples is Symfony\Component\HttpFoundation\Request.
