PHP4 readdir is_dir working incorrectly?

//PHP4 $dir_to_scan = "website.com/htdocs"; $dir_handle = opendir($dir_to_scan); while($filename = readdir($dir_handle)){

       if(is_dir($filename)){
               $files_in_scan[] = $filename;
               }
       else{ echo"$filename is not a directory.<br>\n"; }
       }

sort($files_in_scan); print_r($files_in_scan); The above script properly reports that ".", "..", and "images" are drwx[directories] by adding them to the $files_in_scan array. HOWEVER, my problem is that there are other directories.. quite a few actually.. and above script will say, as an example: pdf_directory is not a directory But I know 'pdf_directory' *is* in fact a directory in 'website.com/htdocs'. Is this a problem with PHP4 or have I somehow 'miscoded' what I'm attempting to do? I would do this in PHP5 but the admin won't upgrade, so I am stuck in PHP4 land w/ this project I am on.
