I assume you are familiar with accessControl standard filter. It allows you to separate privileges to run some action from action code itself. There is however one problem with most common usage - you cannot use bizRules, at least based on some parameters passed to 'checkAccess' just because it is hard to pass them in accessRules() result.
Most of the currently available functions/extensions/behaviors directly or indirectly use timestamps to perform "format" and "timezone" conversions. This creates problems for dates falling outside the timestamp range; and the two forms of conversions must often be done in separate processes. However, by using php's DateTime class (instead of timestamps), we can do both conversions on a single DateTime object (only 2 lines of code) for date, time, timestamp and datetime types - while php takes care of nightmares such as daylight saving times and more importantly, historical changes in timezones and daylight saving times.
As a lead developer at Mutable Labs I was tasked to find a way to do recursive deletion in Yii. As I asked other developers and looked around the internet the usual answers all came up, use a plugin or use cascade delete at the DB level, but I did not want to do either of these.

I installed phpseclib because I needed to do some AES encryption in my project. After all the hassle of installing php lib, I found out that Yii already has a security module (securityManager). I finally decided to keep using phpseclib because it has one big advantage over Yii securityManager module, it does not requite mcrypt to be installed in the phpserver!
The Yii Framework provides a sweet functionality that allows you to easily create page specific menus.
What does this mean?
This allows you to create one layout or CSS styling for your menu, and when each page is loaded, a new set of menu items is loaded in. This is useful for context specific sidebars within your application.
