Separating the data from the display (whatever that is) is prime idea behind the MVC (Model View Controller) design pattern. This way your code that runs via the CLI (command line) can produce the same data as the code that gets the data for the HTML. The only difference is what you plan to do with that data. You could feed it to a controller and let the controller feed it to a View to render in a browser, or send it to a FileOutput class to create a file of the data for comsumption by another resource. -- Bastien Cat, the other other white meat
