```php
<?php
return [
    'components' => [
        'db' => [
            'class' => 'yii\db\Connection',
            'dsn' => 'mysql:host={{db.host|127.0.0.1}};dbname={{db.name}}',
            'username' => '{{db.username|root}}',
            'password' => '{{db.password}}',
            'charset' => 'utf8',
        ]
    ],
];
```

init output:

```
