I’m migrating my app from Slim 2 to 4.
And I saw that there is $request->getParsedBody function to get data sent with $_POST.
What is the advantage of using $request->getParsedBody() instead of using $_POST?
Another question, how do I get data coming from $_GET?
The request object implements the PSR-7 ServerRequestInterface with which you can inspect and manipulate the HTTP request method, headers, and body in a OOP fashion.
You can get the query parameters as an associative array on the Request object using
$params = $request->getQueryParams();
