Doesn't look like there would be a direct conversion. The arrays and functions
used in Javascript are different than what you'd use in PHP. Javascript is also
processed on the client end while PHP is parsed on the server, so it depends on
where you need to do that at.
The Javascript probably allows access to the data in the spreadsheet, so you
might be dependent on Javascript either way to pull the data and send it to the
servers for your PHP code to process.
