Entry script

Initially handles user Requests.

						
						// change the following paths if necessary
						$yii=dirname(__FILE__).'/../yiicore/framework/yii.php';
						$config=dirname(__FILE__).'/protected/config/main.php';

						// remove the following lines when in production mode
						defined('YII_DEBUG') or define('YII_DEBUG',true);

						// specify levels of call stack should be shown in each log message
						defined('YII_TRACE_LEVEL') or define('YII_TRACE_LEVEL',3);

						require_once($yii);
						Yii::createWebApplication($config)->run();
						
					

• DEBUG Mode
• PRODUCTION Mode

Application

Keeps Application Level Configurations ''front-controller''

1. Application Configuration.

2. Application Base Directory.
• protected folder
3. Application Components.
