__FILE__ A magic constant in PHP on Windows that does not return slashes

Question

I am very new to PHP. I was looking for a PHP application that was developed and run on Apache. We move the application to a Windows server running php under IIS. The top of the index.php index has the following code that causes an error:

<?php
	$FileArray = explode("/",__FILE__);
	include_once("/" . $FileArray[1] . "/" . $FileArray[2] . "/theapp/api/MainTemplate.inc.php");
	include_once("/" . $FileArray[1] . "/" . $FileArray[2] . "/theapp/class/User.class.php");

?>

Run codeHide result

When I check __FILE_ with a warning, it shows all the way without a slash.

<?php
echo '<script language="javascript">';
echo 'alert("'.__FILE__.'")';
echo '</script>';
?>

Run codeHide result

, , c:\directory\subdirectory\theapp\index.php, c: directorysubdirectorytheappindex.php

, , :
: Undefined offset: 1 C:\Directory\\theapp\index.php 3

, ?
