If you just want to static-serve the assets in a particular folder, and have
python available, there's always:
python -m SimpleHTTPServer
…which serves the current directory on localhost:8080. But no PHP.
For a modern approach you might look at building a small server based on
Node.js, which is a sort of construction kit for network applications like web
servers, among other things. It runs on small linux platforms like the
Raspberry Pi, as well as the usual desktop systems. Open source at
http://nodejs.org
As an example, I publish an open-source Node.js application for controlling the
Arduino here:
https://github.com/billroy/bitlash-commander
It's a web server that talks to devices on the serial port and serves control
panels with status indicators and controls over the web.
Your DDS control example would be easy to implement in a similar way using
node. Happy to follow up off-list.
