Add PHP file_exists

Sorry for the late reply! I'm okay to merge this, but can you please run yarn fix in your branch?

I don't remember where or why I needed this, but I imagine I solved it by another way.
I get error locutus@2.0.29: The engine "yarn" is incompatible with this module.

Ah sorry about that, I relaxed the constraints there this morning. I wonder if the lock file is gonna cause you issues you. If so, best use corepack yarn instead of yarn and I think on a recent Node.js, the correct yarn version will be used then.

Done
