Requirements Yii Framework

After installing Yii, you may want to verify that your server satis es all the requirements
of using Yii. You can do so by accessing the requirement checker script at the following
URL in a Web browser:
http://hostname/path/to/yii/requirements/index.php
The minimum requirement by Yii is that your Web server supports PHP 5.1.0 or above.
Yii has been tested with Apache HTTP server on Windows and Linux operating systems.
It may also run on other Web servers and platforms, provided PHP 5 is supported.
