The shared nothing request model leads to laziness. And once you get to any kind of scale you'll want to run PHP in something like php-fpm with lighttpd or nginx, which actually does aggressive caching. It's painfully slow to re-evaluate for every single request. This introduces subtle problems because your code was probably shit to start with. Of course, this is not a post about how good or bad PHP is/was. It's just a matter of personal preference at the end of the day. Your favorite language is the one you feel you're the most productive in and says a lot more about you and your experience/background than the language itself.
