Thank you for this. It's a good starting point.

I'm trying to use it to run phpstan against our custom drupal modules, adapted for our folder paths. My commandline looks like this:

vendor/bin/phpstan analyse -c build/phpstan.neon web/modules/custom --level=4

However, I'm still getting errors on most (but not all?) of my custom module classes telling me that <classname> was not found while trying to analyse it - autoloading is probably not configured properly. .

This bootstrap does set up autoloading, but I looked at the autoloader and it doesn't seem to know about the modules folder. Do I need to add something else?

I resolved the above by adding:

    autoload_directories:
        - %rootDir%/../../../web/modules/custom

to the parameters in phpstan.neon.
