Description:
------------
For example in apache configuration you have a restriction like and you are in safe mode :
php_admin_value open_basedir /home/httpd/html/:/tmp/


Reproduce code:
---------------
if you want to check if a file is present or not
file_exists("test.txt") and this file is not present in the directory /home/httpd/html/, you have the open basedir restriction warning.

But if I do the same thing in a subdirectory inside the restriction it is OK. It is not OK only in the directory /home/httpd/html/.

Expected result:
----------------
no warning

Actual result:
--------------
you have the open basedir restriction warning
