PHP Web Server

Now you can PHP while you PHP! http://nanoweb.si.kz/

But seriously, who the fuck writes a web server in PHP? Were they so impressed by the clusterfuck of a language they had to use it?

I might install it as a joke at work, and see how long it takes for our websites to fall over.

I have heard a lot of hate on php but I have heard no valid reasons or alternatives. Hipster programmers
