Description:
------------
Hello everyone,

I have a problem with my installation of PHP 5.2.11 (please see my
configuration below)

I'm using require_once to include twice the same file. In one case I'm
including the file based on its relative path and in other case I'm
including it with its absolute path.

When I use the php client in command line, it works fine. I only have the problem using Apache server.

I figured out that realpath can't resolve the relative path:
<?php
   print realpath("./file2.php") . "\n";                  ==> FALSE
   print realpath("/absolute/path/to/file2.php') . "\n";  ==> /
absolute/path/to/file2.php
?> 

Thank you in advance

Reproduce code:
---------------
file1.php
<?php

require_once('./file2.php');
require_once('/absolute/path/to/file2.php');

$a = new A();

file2.php
<?php
class A
{
    public function foo() { echo 'Foo'; }
}
?>

Expected result:
----------------
The second call to require_once does not include the file.

Actual result:
--------------
PHP raise a Fatal Error : "Fatal error: Cannot redeclare class"
