[CMenu] offers great functionality and the ability to customize just about every aspect of the output. There are many times when I need to create a drop down menu or simply modify the look to make the designers happy.

Please consider the following Dear software engineers imagine I have a simple ISA hierarchy: parent A with children B and C. So let's say we have the corresponding tables named "a", "b", "c" and (created with the help of the gii model creator) the classes A, B, C The following is a screenshot from MySQL workbench: 任务，像每天晚上执行缓存清理，临时文件清理，发送邮件，网站备份等等，重复的工作都交给服务器后台去完成，Yii本身已经提供了强大的支持，我们所做的工作就很少,当使用yiic webapp 自动生成工程结构时，强大的Yii已经全部帮我们生成好，仅仅只需三步。
当我们使用Yii数据库去保存Session时，只要简单的配置就可以完成这个功能，在进行性能优化这个主题之前，我们先来查看一下CHttpSession和CDBHttpSession源代码，探讨CHttpSession和CDBHttpSession的流程再进行深一步优化主题。
上一篇 关于 Yii CHttpSession性能优化篇之源码流程分析 有详细分析CHttpSession执行流程，在了解CHttpSession的详细执行流程之后，我们就可以非常轻松的扩展Yii Session，来优化和符合自己的业务流程。
If in your application you have to proceed to a complex SQL query that is not associated to a model, you will use CDbDataReader like it is described in the Yii documentation. An example could be

CFormatter is one of Yii's core components and used to format values displayed in widgets like CGridView or CDetailView. All classic formats like numbers, text, urls or datetime are supported but you may have to use a formatting rule that isn't built in. Let's say we want to display arrays of strings (like tags associated with a product model)...
