there is another proposal which might also fix your problem: #1469

the PR will use a better default logic so phpstan will in the end use a separate result-cache per phpstan-config.

could you check whether this would also work for you?

@staabm that seems to be a different usecase. I would actually want different cache directories depending on the context the analysis is running in.

Hi, environment- and machine-specific configuration options are already possible via: https://phpstan.org/config-reference#multiple-files

Alternative proposal and more general one is to allow any environment variable to be referenced in the configuration.
