I think people are comparing apples to oranges. Ruby on Rails is as some have stated, a framework, much like Zend or cake or CodeIgniter.
I think the author is spot on in this post. PHP is not without its warts, but as a programming language for web development, it is scalabe, reliable and robust.
Can you perhaps do things faster or more elegantly in other languages? Sure, but writing good clean code is really in the hands of the developer. I can do everything in python because its written in python doesn't mean that that code is going to be designed well or scale well.
"Scalable" and "reliable", perhaps. "Robust" actually means something, though, and PHP is not it. Its wretched approach to error handling prevents that.
