PHP is an extremely powerful language for building websites and has come along way since it's original release, such as object-orientation, etc.
Admittedly, PHP has many flaws, such as poor error handling (for a newcomer, most veterans in this language know them off by hand and actually find them useful) and poor function naming, some are CamelCase, some are under_scored and some are illegiblyalloneword, but every language has flaws.
This is really the kind of cool-kid attitude which HN doesn't need, it shows a lack of due thought and that you have little to no experience of the language itself, if you had, your comment would have been. "This article was on HN 6 months ago, but, I believe that RoR is better than PHP for these reasons... " and not simple "PHP sucks."
