The language brings a culture and the efficiency of a language is indissociable from its average programming culture.
The rant of torvalds against C++ for coding is not about the language but the culture of the developers. http://article.gmane.org/gmane.comp.version-control.git/5791...
The same rant can be made on PHP and this code is just a very vivid example of this point.
PHP is not a fractal of bad design, a language is primarily a media to convey ideas and concept from human to humans and actually if the culture of the users is sub level, whatever the quality of the language is the code will be shitty.
PHP has attained a critical mass of ignorant developers that are dragging not only their whole language down but also of the whole eco system (managers, sysadmins...), so PHP is not only a bad language it is also a bad culture we should try to eradicate :)
