While API development I tried to guess the response status code of requests in a error handler. In most of the known frameworks in the PHP universe there is an error handler, where I get a Throwable and there is a Throwable::getCode() (documentation).
From my point of view this code is more an identifier, than a status code. My best practice is using the current timestamp as code, so I can find the corresponding place in my source code very fast. If I need a return status code I would extend the exception and add a statusCode property.
After a research I saw so many solutions, where developers use the code as return status code. So I am interested in a something like a default PHP exception mapper to status code without using the existing code as status code or at least a best practice to do so. Is there a open source solution or am I on the wrong path?
