Is this some kind of php content generator?

I keep getting sites like this popping in my Google alerts. When you go to the main pages of the site this php page never has any relation to what the site was about so it must be some kind of autogenerated crap right?

Does it work to improve SEO at all or is it some gimick?

Looks like rotating keyword lists

Does that actually help seo at all or is it some kind of old gimick that people dont know doesnt work anymore?
