Need suggestions on PHP frameworks

Hi, I need to select a PHP framework for a small project about 20-25 pages (but expected to grow in the future). I was looking at the comparison chart at http://www.phpframeworks.com/. After browsing through some forums seems like CodeIgniter is the popular option. *** But I really like event driven capabilities in Prado and Yii. *** Please give me your input on what you think the best framework is and why. Also I would like an IDE (preferably free) which support that framework and gives syntax highlighting and auto completion not only to the framework but using my own classes as well. Also it need to have debugging, call stack, variable/object quick view analysis. Thanks, Dhanushka.
