Feature Request

As a long-time vendor of some popular open-source software, I've wanted for a long time something like Babel.js for PHP. Something where I can write code for PHP 8.x, then transpile it back to older versions of PHP that my customers run.

This appears to be doing the exact opposite. :) But, the logic here to move a project in one direction is very similar to the logic required to move in the other direction.

So that's the request — a project that allows me to write clean, modern code, then transpile it back to older versions of PHP so that customers can run it in their — likely older — environments.

(I'm not saying that running EOL versions of PHP is in any way a good idea. But reality dictates that customers like this exist, and I've love to support them without hating life.)
