First of all, as mentioned below if the server advertises PHP support, it's considered that the page is made with PHP (so a standard Apache install that comes with mod_php will make it think you're using PHP). And second, I put my company's (admittedly not YC, but hey) homepage there just to try and since we're using a hosted Wordpress for the landing page so that business people can change the copy easier, it thought we're using PHP when in reality the app doesn't have a single line in it.
