On the ZFort Group's site today there's a new post sharing an infrographic about frameworks in PHP. The data was gathered from Google Trends and looks at popularity and provides some detail for each.

There is a great deal of frameworks, PHP ones in particular, fighting for developers attention. Zfort Group is an interested party in terms of choosing the best PHP frameworks for our custom PHP projects and internal ones as well. So we are continually investigating trends, developers' voting, forums, reviews, ratings, etc. We collected unique and very interesting information and it could be really helpful to the PHP community.

They pulled in some data from other sources as well. It's interesting to see which of the options came out highest in the numbers. They looked at trends for Yii, CodeIgniter, Zend Framework, CakePHP and Symfony. They detail some of the features of each framework including the required PHP version, complexity and quality of community/documentation.
