is_file loop failing

[Anon]

I'm posting here because i don't think this is a windows issue - I am running php 3 on a windows box... with that in mind here's the problem. I am trying to print out the contents of a drive from a user input form.

It's reading the contents... i can print out the files and directories BEFORE the is_file and is_dir statements. But it won't even enter the is_file and is_dir loop.

$handle = opendir($drive) ;

$fileCounter = 0 ;
$dirCounter = 0 ;

while ($file = readdir($handle)) 
{
             if ($file != "." && $file != "..")
   {	
       if (is_file($file) )
       {
            echo "in File loop" ;	
                      $allFiles[$fileCounter] = $file ;
            $numFiles = sizeof($allFiles);
            $fileCounter++ ;
        }

         if (is_dir($file) )
         {
	echo "in dir loop" ;
	$allDirs[$dirCounter] = $file ;
	$numDirs= sizeof($allDirs);
	$dirCounter++ ;
         }
    }
}

closedir($handle);
