New to Rails / Dont know PHP. Advice?

I wonder if you are confused about Rails and think that is related to
php in some way. Rails is nothing to do with php but is based on
Ruby. In depth knowledge of Ruby is not required to get started
however. Work through a good tutorial such as railstutorial.org and
you will learn the fundamentals of Ruby at the same time as Rails.
Your knowledge of jQuery, javascript, html and css will be invaluable
however.
