From what I recall I've seen while browsing
through its source, wdiff
just transforms every space in a file into a newline, then runs diff on
it. This could be simulated in PHP too.
diff isn't reliably available either. It won't be present on Windows,
and will often be inaccessible on Unix (because of exec() being
disabled or such).
But the reformatted text could be diffed the same way ordinary text is now.
