Combine some of the PHP into a "single page application"

[lionello]

Got quite a lot of files now, with redirects back and forth. Could write it as a few simple SPAs instead.

Not important.

Can we use Composer to simplify that? And is it possible to use .htaccess or a specific configuration of the web server to define the routing? In fact, what are the constraints of this application?

[lionello]

Anything is possible. I don't know Composer and I don't think we'd need any server side routing. I was thinking to make a single (or perhaps two) html pages, which then use one or more APIs server side (PHP or other) using xhr/jquery. It's not really important, since the system works fine as is.

Requirements: as little server side dependencies as possible, to make it easy to port. I wouldn't use any state-of-the-art tech.
