$logger = Yii::createObject('\yii\log\Logger'); $logger->log('This is a log message');
$config = [ 'class' => '\yii\db\Connection', 'dsn' => 'mysql:host=localhost;dbname=mydb', 'username' => 'myusername', 'password' => 'mypassword', ]; $db = Yii::createObject($config);In this example, we are configuring the options for creating a new instance of the Connection class from the Yii DB package library. We then call the createObject method with the $config array to create the $db object. Overall, the createObject method in Yii is a powerful tool for creating new instances of classes and objects with flexibility and ease. The package library referenced in the code examples is the Yii framework itself, which contains numerous packages for different functionalities in web development.
