Please tell me when you want to reflect the template, I made a mistake. The c error is Fatal error: Class 'Think\Controller' not found in

Question

<?php
namespace admin\Controller;
use Think\Controller;
class IndexController extends Controller {
   public function index(){
       $this->show('12345667',utf-8);
   }
}

Answer 1

It may be related to the code compiler you are using. I will report this error when I use HBuilder to read and modify the box on the right side, but it will display normally when browsing with a browser.

Answer 2

What you wrote was for TP3.2, but now you are teaching for ThinkPHP5.0~

Answer 3

Is the controller written wrong?
