include() function in PHP behaves differently on XAMPP update

问题

My files structure are :

/ (Root)
|-- includes
|-- |-- global.php
|-- |-- config.php
|-- index.php

In my index.php file I wrote :

<?php
include "includes/global.php";
?>

and in includes/global.php I wrote :

<?php
include "config.php";
?>

the global.php in index.php will be include whitout any problem but config.php in global.php will not be include !

I use XAMPP and in my old version of XAMPP (version 1.7.3) I don't have any problem but today I installed new version of XAMPP (version 1.8.1) and I have this problem !

I should use absolute path for including config.php file in global.php but I don't want to use absolute path, I want to include like before, how can I do this ?

回答1:

Check your include_path. You need to add "." to it.

Or you can define it in runtime.

set_include_path(get_include_path() . PATH_SEPARATOR . '.');

回答2:

The path in include is always relative to the top-level script. So your second (nested) include will not resolve correctly.

A common workaround is to use:

<?php
include dirname(__FILE__)."/config.php";
?>

inside includes/global.php. This will make the path resolve correctly, no matter where the toplevel script is located.

回答3:

global.php,

write

include "includes/config.php";

回答4:

I was having the same issue, but don't really want to use a workaround, so I tried a few things and discovered that the code I'm working on is written with old style php opening tag, i.e. <?

As soon as I changed it to <?php the includes worked.
