The answer depends on the purpose of the project. If you're building something to make money, you should not spend the time now to switch languages unless your NEW language has some library or feature which your current project simply cannot work without. However, if this is a learning exercise only or just a fun project, there would be no harm in spending the time to explore both the Python and Ruby options. The key to your decision here should be how much time and effort it would require to duplicate a feature you want to use in your existing system as compared to what comes out of the box with either a new language or an existing PHP framework. If it's a pain to do and the functionality is critical to your project's success, then you should port. Otherwise, I'd recommend you keep doing what you're doing.
