What is this (new someClass($_POST));?

Question

PHP

I noticed the following code in one project:
(new someClass($_POST)); ?
do we just create an object without assigning it to any variable? In theory, we only need the __construct function to work.
what is this approach called or what to read on the topic? where else is something like this used?

Answer 1

Most likely, the variable is passed to the constructor by reference, and how it is processed.
Bad option.

Answer 2

The approach is called govnokod. Read - any article from Google on request.
