On StackOverflow.com what started out as a question about framework choices has turned into a good discussion about preferences, features and thoughts on several including the Zend Framework, CodeIgniter, CakePHP and Symfony.

Over the course of your web development experience, what PHP framework(s) have you worked with? What strengths and weaknesses have you observed in those frameworks? Considering these, what framework would you recommend if beginning a new application?

Fans and developers from most of the popular PHP framework have contributed their two cents into the discussion including links to other resources showing "versus" comparisons and even a mention or two of Ruby on Rails.
