Description:
------------
Create and Manipulate NTFS Junction Points doesn't work in PHP but it was solved by www.sysinternals.com. They also offer the c-code free for download.

I have tested it and it works very well.

You can download the free source code there:

http://www.sysinternals.com/files/jnctnsrc.zip



Reproduce code:
---------------
$letters = 'abcdefghijklmnopqrstuvwxyz'; 
srand((double) microtime() * 1000000); 
$string = ''; 
for ($i = 1; $i <= rand(4,12); $i++) { 
   $q = rand(1,24); 
   $string = $string . $letters[$q]; 
} 
//----- this part can't work under windows
$handle = opendir($downloaddir); 
while ($dir = readdir($handle)) { 
   if (is_dir($downloaddir . $dir)){ 
     if ($dir != "." && $dir != ".."){ 
         @unlink($downloaddir . $dir . "/" . $filename); 
         @rmdir($downloaddir . $dir); 
     } } } 
closedir($handle); //------
mkdir($downloaddir . $string, 0777); 
// here symlink produce browser crash under windows
symlink($safedir . $filename, $downloaddir . $string . "/" . $filename); 
Header("Location: ".$downloadURL.$string. "/" . $filename);

Expected result:
----------------
start downloading but produce browser crash

Windows versions of PHP don't even have symlink(), readlink(), linkinfo() or link(), so it can't possibly be crashing.

I'll accept your feature request for NTFS junctions, but can't do anything about it until we are developing PHP 5.1.
