You still have to deploy to Lambdas.

I believe the post you're responding to was alluding to the degree to which a lot of single-file PHP/HTML is written in a very "serverless-esque" way: no dependencies on an outer framework, and likely scales quite far compared to other languages when run on any number of servers (with the required libraries).

In addition to what you mentioned, with PHP there's no need to start, restart, monitor, or otherwise manage your own daemon. Apache and/or PHP-FPM does that for you.
