I have a controller that runs the index method for the main page. A button in profile information is called by a route that falls into the cadastre method. Is the instance that was run when the index was still running when I am running another call via get? Or does she go to each new request?

HTTP is a stateless protocol .
Briefly means that each request is an independent transaction.

The entire process in PHP is compiled at runtime and "dies" when the build is complete.

On a second request, a new process starts completely independent of processes executed on previous or subsequent requests.

However, there are several techniques for keeping a "live" instance on separate requests.

Obviously this is not only in PHP. It is the nature of the HTTP protocol.
