Does anyone know of a php news publishing script that can be integrated into an existing site (not a cms script) that includes the comments inside the news posts at all times?

In other words, you don't have to view the full story or load a new page to view comments as they are already displayed on the initial post, along with the comment submission form.

What is the problem to write such script yourself? It is a matter of half an hour. The logic is so simple that you will spend much more time on searching for that script and correcting its initial bugs than on developing it from scratch.

I'm not a php developer.
