File not found.

[haylinmoore]

I copied the first example from the readme file, the one thing I changed was serveStatic(process.env.FOLDER). It works for serving static files, but the minute I try to run test.php which simply contains

<?php
    phpinfo();

I get the error File not found. spit out to the client

and with all requests I seem to be getting
