Yii Migration Issue

I am new to PHP and Yii PHP Framework.

I am trying to run an application in my local machine. For which i first need to migrate Database. For which i run following command,

protected/yiic migrate

But it throws CDbException with following Stack Trace ...

Yii Migration Tool v1.0 (based on Yii v1.1.14)

exception 'CDbException' with message 'CDbConnection failed to open the DB connection: could not find driver' in /var/www/Prepaid-Card/web/framework/db/CDbConnection.php:382
Stack trace:

#14 /var/www/Prepaid-Card/web/protected/yiic(4): require_once('/var/www/Prepai...')

And here is my console.php file

<?php

return array(
    'basePath' => dirname(__FILE__) . DIRECTORY_SEPARATOR . '..',
    'name' => 'Prepaid Card',
    // preloading 'log' component
    'preload' => array('log'),
    'import' => array(
        'application.models.*',
        'application.components.*',
        'application.extensions.*',
        'ext.YiiMailer.YiiMailer'
    ),
    // application components
    'components' => array(
        'db' => require(dirname(__FILE__) . '/../../../../DbConfig.php'),
        'log' => array(
            'class' => 'CLogRouter',
            'routes' => array(
                array(
                    'class' => 'CFileLogRoute',
                    'levels' => 'error, warning',
                ),
            ),
        ),
    )
);

I have already installed mysql and have created the subsequent database. My DbConfig file looks like

<?php
return array(
    'connectionString' => 'mysql:host=localhost;dbname=db_ppc',
    'emulatePrepare' => true,
    'username' => 'root',
    'password' => 'helloworld',
    'charset' => 'utf8',
);

I just couldn't figure out the issue here.

What i am doing wrong here ? What could be the cause of this issue ? Please help me to solve it.

Thanks!!!

"CDbConnection failed to open the DB connection: could not find driver". This message tell u that something is not good configured on your environment. Check your php configuration for database driver and restart/reload your apache to load new configuration.
