ThinkPHP5 Introducing Templates

There are three ways to do this:
First:  direct use of return  view ();  Helper functions
The second kind: use  think\view;    Class Admin extends view   see below
The Third Kind: use   think\controller;  Class Admin extends Controller    return $this->>fetch ();

<?php
namespace App\admin\controller;
Use Think\view;      The second Kind
Use Think\controller;  Third Kind
Class Admin extends View
{
    Public Function LST ()
    {
        The first method loads the template using the helper function to configure the template suffix in config is  the simplest
        return  view ();
        The second method loads the template, you need to specify the suffix format  config invalid use Think\view  extends View
        $view =new View ([' view_suffix '  = ' htm ',]);
        return $view->fetch ();
        The third kind of use Think\controller;   Configure the template suffix   extends Controller in config
        return $this->>fetch ();
    }
}
