directory script problem 1

[IDTstudios1]

The following script keeps puting dots before the actual directory. Basically it outputs:

<a>.</a><br><a>..</a><br><a>testone</a><br><a>testtwo</a>

when it should output:

<a>testone</a><br><a>testtwo</a>

Script:

$dir = "albums/";

if (is_dir($dir))
{
if ($dh = opendir($dir))
{
while (($file = readdir($dh)) !== false) //while files and folders are being read
{
if (filetype($dir . $file) == dir) //if the filetype is a directory and not a file
{

echo '<a>' . $file .'</a><br>';
}
}
closedir($dh);
}
}


Any help would be great,
Thanks

um, that's because the first two files in EVERY directory are the "." file (which means "the current directory") and the ".." file (which means "the directory above this one"

Its why you can do things like "cd .." literally "change directory to the directory above this one" and "move file_to_move.txt ." which means move this file to the current directory. Its a remnant of the FAT file system.

go to a command prompt and type "dir" and you'll see the same thing.

The only way to get rid of them would be to basically say

        if (filetype($dir . $file) == dir) //if the filetype is a directory and not a file
         {
             if ($file != ".") && ($file != "..") )
             {  
                  echo '<a>' . $file .'</a><br>';
             }
         }

Thanks, I had totally forgotten about that.
