Can't include php class

Question

This is my directory structure:

classes
- myphpclass.php
controller
- controller.php
index.php

Now, I want to include myphpclass.php in my controller, but I don't know how to path it.

I'm trying something like include('classes/myphpclass.php');

But I can't make it to work

Answer 1

require_once(dirname(__FILE__).'/../classes/myphpclass.php'));

更好的使用require_once： require，include和require_once之间的区别？

Answer 2

使用正斜杠启动所有路径 - 然后它们都与ROOT相关。

include('/classes/myphpclass.php');
