How to properly set up an error handler like filp/whoops in a project without a framework?

Question

PHP

I like the built-in error handlers in Laravel and Symfony - it's immediately clear and understandable what's wrong and where the legs of the exception grow from.

I tried to tie something similar to a project that is "from scratch" - i.e. just a regular Composer, and I wanted to take https://github.com/filp/whoops/ as a basis - but it didn’t happen :) It was useful to see an example:

https://github.com/filp/whoops/blob/master/ example...

and it broke my brain)))

Tell me, is there something similar, but only simple to set up?

I really want to have such a thing during development, but at the same time not spend more time on setting it up than on the work itself.

Thank you.
