Yii Database Operations

1. Example: Create a class that inherits from the activity record class Country and put it in a models/Country.php file to represent and read country data from the table.

<?phpnamespace app\models;use yii\db\ActiveRecord;class Country extends ActiveRecord{}

This Country class inherits from Yii\db\activerecord. You don't have to write any code in there. Just like now, Yii can guess the corresponding data table name according to the class name , the default table name is the class name.

Note: If the class name and the data table name do not correspond directly, you can override the TableName () method to explicitly specify the related table name.
