I am new to the concept of Ruby on Rails, but familiar with a variety of web development scripting languages such as ASP, PHP, CFML.

From skimming the web I gather that Ruby on Rails allows you to structure your information in a certain way so that the scripting language can do allot of work for you?

Is this accurate?

If you wanted to create a simple 5 page mostly static web site, how usefull would Ruby on Rails be for something like that?

Is Ruby on Rails only usefull when developing larger scale apps or can simple one page web apps be deployed rather easily?

Why isn't there a PHP on rails (or is there?)

Thanks for the help, trying to decide if I should make the plunge and try and learn Ruby on Rails.
