relative path in require_once doesn't work

Question

I have the following structure

otsg
 > class
   > authentication.php
   > database.php
   > user.php
 > include
   > config.inc.php
   >         


        

Answer 1

Use

__DIR__

to get the current path of the script and this should fix your problem.

So:

require_once(__DIR__.'/../class/user.php');

This will prevent cases where you can run a PHP script from a different folder and therefore the relatives paths will not work.

Edit: slash problem fixed
