True, that's pretty easy. But it's also just as easy as getting most other language or frameworks up and running. And since the argument I was replying to was that PHP was good because those other languages are too hard to configure then, implicitly, PHP is too hard to configure - at least for the guy I was replying to.
And if you're relying on your webhost having your language-of-choice already configured for you, well, you can find webhosts with most of the obvious choices already configured. So what does that leave?
I would suggest that PHP does not, today, have any advantage over other competing languages and frameworks in the "it just works" sweepstakes.

Looks pretty easy to me.
Then again, I compile my own version of Apache with FastCGI and PHP-FPM all the time.
