I'm trying to make a Web site that showcases multiple scripting languages, including Ruby on Rails. If I make the framework of the site in Rails, is there a way to run other languages like PHP on the Rails server, or do I need something like XAMPP?
For example when you want to run perl, you could use Microperl. For php.
If this all does not work for you or you want to execute it otherwise, you can create APIs in such languages and let Ruby talk to this APIs.
