How to mix php and ruby / rails

I have a php web application. I also have a ruby / rails application.
I want to have the ruby / rails app generate it’s output within a

section in the php web application. Is this possible?

Normally, you can have a function generate html within a

section
because the server generates the html code. So, can I have a ruby /
rails application send its stuff to the div section in a php based
site?
