YII学习总结6（模板替换和“拼合”）

controller\helloController.php<?php	namespace app\controllers;
	use yii\web\Controller;
	class helloController extends Controller	{		public 	$layout = "common";
		public function actionIndex(){					return $this->render("index");//renderPartial功能简单，只替换模板变量，render拼合模板				}	}?>
view\layouts\common.php	<!DOCTYPE html>	<html lang="en">		<head></head>		<body>			<h1>common view</h1>			<?= $content;?>		</body>	</html>
view\hello\about.php	hello about!view\hello\index.php	hello index!
