counting number of files from a remote server

I want to count files from a directory which is stored in a remote server .
I used the following code . But obtained warning

<?php
$url='192.168.0.138/img/12/12N69/';
$dir = opendir($url);

//List files in images directory
while (($file = readdir($dir)) !== false)
  {

  echo "filename: " . $file . "<br />";
  }
closedir($dir); 
?>

Warning:
Warning: opendir(http://192.168.0.138/img/12/12N69/) [function.opendir]: failed to open dir: not implemented in C:\xampp\htdocs\divya\remote_files\remote.php on line 3

Warning: readdir() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\divya\remote_files\remote.php on line 6
filename:

From the manual:

"If path is not a valid directory or the directory can not be opened due to permission restrictions or filesystem errors, opendir() returns FALSE and generates a PHP error of level E_WARNING. You can suppress the error output of opendir() by prepending '@' to the front of the function name."

So, because your $url is missing file:// or ftp:// you get the error. Either that, or a permissions issue. As stated in your previous post on glob, you will need to find another way to do this.
