Description:
------------
Problem with openDir/readDir:
A folder with the name "0" breaks openDir/readDir.

Sometimes you will have different orders,
but the script breaks on the folder with the name "0".

Tested on PHP 5.4 and 5.3 on different Webservers. (IIS + Apache) and different OS (Win7 + WinXP)

Test script:
---------------
<?php

$verzeichnis2 = openDir("//fileserver/Daten/");
while ($file2 = readDir($verzeichnis2)) 
{
	echo $file2;
	echo "<br>";
}

?>

Expected result:
----------------
folders:
.
..
0
1
2







Actual result:
--------------
Output from the example-script:
.
..


If you rename the Dir "0" to "X0" the output looks like:
.
..
X0
1
2

This function(readdir) may return Boolean FALSE, but may also return a non-
Boolean value which evaluates to FALSE. Please read the section on Booleans for 
more information. Use the === operator, see: 
http://www.php.net/manual/en/function.readdir.php

which means you should write your code  like :

while (($file2 = readDir($verzeichnis2)) !== FALSE) 
{
	echo $file2;
	echo "<br>";
}
