Demo7中test4代码：

namespace app\index\controller;

class Demo7 extends Controller

//1.直接将内容输出到页面，不通过模板
public function test1(){
$content = '<h3 style="color: red">php中文网欢迎你</h3>';
// return $this->display($content);
return $this->view->display($content);//推荐这种方式
return View::display($content);//静态代理
}
// 2.使用视图将数据输出：fetch()
public function test2(){
// 模板变量赋值：assign()
// 1.普通变量
$this->view->assign('name','peng');

//批量赋值
$this->view->assign([

// 2.array 数组
$this->view->assign('goods',[

// 3.object 对象

// 4.const 常量

// 在模板中输出数据
// 模板默认的目录位于当前模块的view目录，模板文件默认位于以当前控制器命名的目录中
