#44293 [Fbk-Opn]: realpath does not follow Virtual directory
ID: 44293 User updated by: mmichel at chez dot com Reported By: mmichel at chez dot com -Status: Feedback +Status: Open Bug Type: Filesystem function related Operating System: Win2003 PHP Version: 5.2.5 New Comment: yes there is. Elsewhere could be accessed with ../../Elsewhere from the root directory of the website. Virtual Directories in IIS try to mimic symlinks, but they are not real files that can be tracked down like symlinks. This may be the problem determining the realpath. Previous Comments: [2008-03-05 09:28:21] [EMAIL PROTECTED] So is there some path in your filesystem called Elsewhere which is relative to the current working directory? If there is, then this is a bug, but if there isn't, then it's not a bug. [2008-03-03 15:03:10] mmichel at chez dot com Try adding the trailing slash in the directory.. No change.

What does this script output:
?php
$local='./local';
$virt='./elsewhere';
var_dump(realpath($local));
var_dump(realpath($virt));
?

Description:
If you do a realpath('./elsewhere'), where elsewhere is a IIS virtual
directory, realpath return FALSE.
Reproduce code:
---
- Use the default site in IIS6 (root=c:\inetpub\wwwroot)
- in the root directory create a folder called local
- Create a virtual directory (either via a network share or in another
path on a local drive, e.g. C:\Elsewhere), and call it elsewhere
then
?php
$local='./local';
$virt='./elsewhere';
$check_path=realpath($local);
print ($checkpath === FALSE) ? local path not resolvedbr :
local=$check_pathbr;
$check_path=realpath($virt);
print ($checkpath === FALSE) ? virtual dir not recognizedbr :
virtual=$check_pathbr;
?
Expected result:
local=C:\Inetpub\wwwroot\local
virtual=C:\Elsewhere
Actual result:
--
local=C:\Inetpub\wwwroot\local
virtual=
Note that realpath does not return FALSE...

@jani:
Virtual dir is kind of a symlink handled by IIS rather than the OS.
Thus, the document_root for http://localhost/elsewhere/test.php is
different from the one for http://localhost/local/test.php
Still, browsing to http://localhost/elsewhere works, and executing
http://localhost/elsewhere/test.php works.

That's your code, note the tiny typo there? :)
From the manual:
realpath() returns FALSE on failure, e.g. if the file does not exist.
I don't know what these 'Virtual dirs' are in IIS, but I guess they're
not _filesystem_ things. realpath() is meant to be used with
_filesystem_..

Moreover:
On this page http://php.uli.it/manual/hk/function.realpath.php
a comment provides this:
=8=
This is a modified version of the code written by Dave, wich finds the
absolute path of a virtual path, this function returns the absolute
path, If you have php running on IIS Plataform you could find this very
usefull
function mappath2($path) {
//this here bellow trims the last / in case it has it
If ($path{strlen($path)-1}==/){
$path = substr($path,0, strlen($path)-1);
}
$relative = str_repeat('../',substr_count($path,'/')-1);
// transforms virtual or relative path to an absolute path
return realpath(substr($path,0,1)=='/' ? $relative.substr($path,1) :
$path);
}
the implementation would be like this
having
$imagepath = /website001/images/catalog/;
$realpath = mappath2($imagepath);
The result in $realpath would be something like
C:\Inetpub\wwwroot\website001\images\catalog
=8=
I tried the function and it did not worked.
