What about true|ZipArchive::ER_* instead?

that works? Hm, I had no idea.

In that case I recommend you to check the documentation: https://phpstan.org/writing-php-code/phpdoc-types#literals-and-constants

the functionMap goes through the same parser.

build failure is bogus, doesn't look related to the PR

Thank you! Let me know if you find out more function types that could be upgraded with constants like this :)

@ondrejmirtes Sure. I'm not actively scouring for them, but I stumble across them quite often during development :)
