Does there exist some sort of PHP server that can be bundled with a locally-deployed application? It sounds wonky, but the end result is I can't use a remote web server to do anything. Clients will be downloading a package, and the plan is to use a Java backend that reads from a flat file. The flat file contains settings and is modified through a GUI written in HTML/JS, and this is where the server would come in. The forms in HTML should be able to submit to the server, which does a simple file write to the flat file.

Is there any simple, lightweight server that has that simple feature? When running the executable for the application, it would start the installation process for the server before moving the web GUI files to the appropriate locations.

Note that I'm doing this for a client, so I can't quite change the reqs and would rather not discuss their effectiveness. I would be ever thankful if people had suggestions for the server though!
