In this post on the Zend Developer Zone, Cal Evans takes a look at an article published in a recent php|architect issue from Chris Hartjes about how several recent advancements in the PHP community have helped developers think more in "the Rails way" of development.
Chris does a good job of laying out his points. As with any article of this nature, you are going to agree with some of them and you'll disagree with some of them. However, to get to that point you'll have to consider all of them. That's really the point of the article; making developer sit back and think for a minute. It's well worth the read.
Cal also mentions some of the topics presented in the article including more conceptual ideas like "Convention Over Configuration" and "Rapid Should Mean Rapid".
