Where in linux ubunta 18.04 when using laravel can temporary files or error files accumulate?

Question

Laravel

I'm not strong in Linux, but I raised and configured the server to run several sites. Then the question arises, where can temporary files accumulate, or maybe some log files of ubuntu itself, as well as the php laravel framework?
The goal is to periodically check these places and not accumulate shit that will take up extra space.
The server uses ubuntu 18.04, apache, mysql, laravel
