How can I implement SEO-friendly URL with php?

I'm currently using Apache HTTP + PHP + MongoDB.

I'm trying to implement "stackoverflow"-like url which is SEO friendly.

Should I read a title from each article and somehow send that to Apache? If so, how can I do that?

So that Apache can handle that the title s开发者_如何学JAVAtring with mod_rewrite and having URL like

www.example.com/123/seo-friendly-page 

Give me some ideas with an example snippet code
