Resolve the PDO disabling issues for Yii on Godaddy hosting

My Yii application uses PDO for database access, which requires the server to have the PDO enabled. However, I am having some problem hosting my Yii application on GoDaddy, since hosting providers suych as GoDaddy disable PDO. After some searching, I found an alternative PHPPDO for Yii, which can be downloaded from:

http://www.yiiframework.com/extension/phppdo/

This extension allow you to use PHP-emulated PDO class on that hostings. The process of including PHPPDO for Yii application is very simple:

Step 1: download and extract the content of PHPPDO to protected/extensions of your Yii application
Step 2: in the protected/config/main.php, commented out the original db connection configuration and replaced with the PHPPDO one, just as in the following:

                /*
'db'=>array(
'connectionString' => 'sqlite:'.dirname(__FILE__).'/../data/testdrive.db',
),
// uncomment the following to use a MySQL database
'db'=>array(
'connectionString' => $ps_connectionString,
'emulatePrepare' => true,
'username' => $ps_dbusername,
'password' => $ps_dbpassword,
'charset' => 'utf8',
),*/
'db'=>array(
'class'=>'application.extensions.PHPPDO.CPdoDbConnection',
'pdoClass' => 'PHPPDO',
'connectionString' => $ps_connectionString,
'emulatePrepare' => true,
'username' => $ps_dbusername,
'password' => $ps_dbpassword,
'charset' => 'utf8',
),
