How to access a thread title and thread body from PHP

[Frank T]

I'm writing a plug in to access an external database based on the contents of a thread title, or post body.

How do I capture the current thread title, or current post body from PHP?

(Yes, I've looked through a bunch of articles...but coming up blank...)

Edit: partially solved.

Post Title: $post['title']
Post body: $post['message'] doesn't seem to work.
