冲突包括具有相对路径的文件

Question

I'm trying to make includes dynamically in my php script. This is my directory tree:

-index.php
-sources/
--hello.php
--bye.php

In my index.php I make an include of hello.php:

include("sources/hello.php");

In my hello.php I have another include of:

include("bye.php");

When I access the index.php it throws an error saying:

Message: require_once(bye.php) [function.require-once]: failed to open stream: No such file or directory

Is there a way to get it works but without absolutes paths? because the paths can be changeable from one directory to another but keeping the structure:

-index.php
-sources/
--hello.php
--bye.php

Answer 1

use

dirname(__FILE__);

like this

include(dirname(__FILE__)."/bye.php");
