This may seem like a daft question, but i was wondering about how to use MVC frameworks on hosted servers.

I am playing about (albeit slowly) at home with the RoR on Ubuntu and understand that if i want to do a live site then i need hosting with Rails and Ruby.

However, what happens about the PHP frameworks. For example i have seen in the past all about the CakePHP but lately i have just come across the Symfony project and was thinking that if i had a server stack set up i could develop at home, how would i go about deploying anything live.

How do i use php command line on live servers, and how would i go about installing the framework on another server.

This is all hyperthetical at the moment as i am just thinking about it, but it is a question that i have thought of in the past.

Regards
