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).
