Here's a real world example of someone making the switch from Ruby on Rails to CakePHP. 

"CakePHP is a web application framework, written in PHP (as all decent web tools are), and is in many ways very similar to Ruby on Rails.

Except it’s lighter (less cluttered), better supported (documentation, examples, etc), and deployment basically involves uploading 2MB of PHP files into a subfolder on your website (considerably easier than getting a Rails APP to run)."
