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!
