Love the prose but shouldn't we try a fix like mentioned in the original issue?

I agree that fixing the issue is better than putting up a sign. I do not know how to proceed though, this is my first attempt to submit an issue, and while I'm somewhat of a php developer, I do hardly know any python and would not know how to create the environment to test this in.

You're doing good here. Hacking on this, would mean

The path when clicking above, in that: git clone https://github.com/SublimeLinter/SublimeLinter-phpcs.git so that you have Packages/SublimeLinter-phpcs. This will take precedence over the official one installed via Package Control. Then open that folder in Sublime, open linter.py and delete the Line 19 (filename=file_path,) or set it to filename="-",. Save, should reload immediately. See if the patch works. Just delete "Packages/SublimeLinter-phpcs" to undo. If in doubt restart Sublime in between.

Yes, that makes it work as expected.

Thanks, you know I can guide you but don't have all the tools and languages installed. ❤️

Excellent!
