How are variables passed to view in popular Frameworks?

Question

PHP

Hello. How are variables passed (better passed) to the view? For example to Codeigniter. $this->load->view('template', $data) but what is hidden there in this view method. How does it load the view and pass parameters. In laravel return view('template', $data) what is hidden behind this? What can be read on this topic or is the only way out is to climb into the source codes of these Frameworks and study?
