Installing Yii Framework in XAMPP

Here I will discuss the details of the installation steps Yii Framework. But before, there are some you need to prepare to install Yii:

• Yii Framework - Download at http://www.yiiframework.com/download/
• Web and database Server, here I am using XAMPP - Download at http://www.apachefriends.org/en/xampp.html
• Web Browser, here I use Mozilla Firefox - Download at http://www.mozilla.org/id/firefox/new/

After you download all, let's start installing yii. Here, I use windows 7 as the operating system.

1. Install XAMPP, here I did not explain how to install it, but just to be safe when the computer error and have to reinstall, it should be installed on a drive other than C, such as drive D, E, or others. Here I installed on drive D

2. Extract yii-x.x.x.xxxxx.tar.gz that you download, then change its name to yii, and to be more easily placed in the folder XAMPP / htdocs, so that such XAMPP / htdocs / yii.

3. Open the comand line by pressing ctrl + r and type cmd
