No, but PHP can run without a server. It runs just fine without Apache or IIS
as a batch job.
He didn't say you could start a browser with it, but you can connect to a remote
http(s) service and have it respond. The local script can then interact with
the retrieved data.

No, at that point PHP is running as an application. Period. If what you say
were true, a machine running *any* application would be a server. A C++ program
could do exactly the same thing the PHP program is doing, for instance. Is the
machine now a "server"? What if you're running a word processor (another
application)?
And no, it doesn't interact with PHP on a remote box. But it can interact with
a web server or similar, just like a browser can. And that doesn't make the
machine it's running on a server.
