Description:

Hi there:

In *WINDOWS*, function include fail when i try :

  include("include\test2.php");

but works with : (take note on \ and / symbol)

  include("include/test2.php"); 
  include("include\\test2.php"); 

This error started when i installed the latest version.
I don't sure if the use of folder\file is a bad practice or not but i don't find this change on the documentation.



Reproduce code:
---------------
file test.php

<?php 
	include("include\test2.php");
?> 

file test2 on folder include

<?
  echo "include!!\n";
?>

Expected result:
----------------
include!!


Actual result:
--------------
