Opendir works only with absolute path

Question

When using following code:

if ($handle = opendir('../flat')) {

}

I'm getting this error:

Warning: opendir(../flat) [function.opendir]: failed to open dir: No such file or directory in D:\Inetpub\webs\mysite\newSite\lib\flat.php on line 1

Using

dirname(__FILE__);

I can see the correct path of my PHP script:

D:\Inetpub\webs\mysite\newSite\lib

Using absolute path opendir works good:

if ($handle = opendir('D:\Inetpub\webs\mysite\newSite\flat')) {

}

What could be the problem? Can someone help me?

PHP's open dir functions don't work with URLs, unless they're full and absolute. Your relative path will not work with open dir unless it is a file directory or absolute path like http://www.example.com/blah/blah..

According to the PHP manual:

a) path supports the ftp:// URL wrapper.

b) path can also be any URL which supports directory listing, however only the file:// URL wrapper supports this in PHP 4
