```php
echo $this->render('renderer.tpl', array('username' => 'Alex'));

### Additional functions
Additionally to regular Smarty syntax the following is available in Yii:
```php
<a href="{path route='blog/view' alias=$post.alias}">{$post.title}</a>

### Additional variables
- `$app` = `\Yii::$app`
- `$this` = current `View` object
