在CodeIgniter子文件夹中需要一个类？

Question

I have this structure

controllers
- base.php
\ subfolder
  - home.php

in home.php I want to call

require("../base.php")

but it gives me an error message saying the file was not found. On the same folder it works.

Is there a way to get it working on the subfolder?

Answer 1

CodeIgniter is executed from within index.php script and paths of require function are resolved based on index.php path. For example if you would put test.php in CodeIgniter root folder and then you would call require './test.php' from your controller then the test.php would be included without a problem.

To answer the question we need php magic constant __DIR__ which is always set to current script folder. The answer is:

require __DIR__."/../base.php";

called from within home.php.

Edit: And platform independent solution would be:

require __DIR__.DIRECTORY_SEPARATOR."..".DIRECTORY_SEPARATOR."base.php";
