with enabled safe-mode and open_basedir restriction it is not possible to execute a include/require/... function in a included file that tries to include a file that is in a subdirectory of the initially executed script.

WORKAROUND: Placing all included files into the same directory works fine, but is quite a bunch of work and not always suitable when adapting supplied software and scripts, e.g. running phpNuke in this environement.


example:

in documentroot: file test.php:
<?php
require_once ('test/1.php');
require_once ('test/2.php');
require_once ('test/3.php');
?>

in the subdir test:
1.php:   <?php include ('3.php'); ?>
2.php:   foo_2
3.php:   foo_3

error:
Warning: open_basedir restriction in effect. File is in wrong directory in /home/sites/x/www/test/1.php on line 1

Apache's httpd.conf sets this param:
php_admin_value open_basedir /home/sites/x

open_basedir is tested and working fine, except those nested includes.
