We looked at lightweight frameworks and went with Yii (http://www.yiiframework.com/). CodeIgniter is getting a bit long in the tooth. Yii is a modern object oriented framework.
Yii uses demand loading of classes to avoid the performance problems of object oriented frameworks which load all the files off the disk for every request (see http://talks.php.net/show/froscon08). And it uses prepared statements for SQL, improving performance and avoiding SQL injection attacks.
It's nice for simple applications, but lately has been growing to include other features.
