They both try to lower the bar for a person to become a productive web developer. Dhh (Rails creator) calls it "conceptual compression". But in reality, to build anything half mature you not only have to know how to program, you also have to understand the concepts Rails supposedly compresses. The complexity is still there. The best example I have for this fallacy is the notion that ActiveRecord can make SQL obsolete thus make the framework easier for beginners. Dhh advocates this and it's absolute horse shit. But yes, both Rails and php are beginner friendly, that has pros and cons and comes with a reputation.
