YII总结学习7（在一个视图中显示另外一个视图）

controller\hello
<?php
    namespace app\controllers;

    use yii\web\Controller;

    class helloController extends Controller
    {

        public function actionIndex(){
        
            return $this->renderPartial("index");
        
        }
    }
?>


view\hello\about.php
    hello about!
    <?=$v_hello_str;?>

view\hello\index.php
    hello index!
    <?php echo $this->render("about",array("v_hello_str"=>"hello world!"));?><!--视图组件 $this -->
