look at the below code:

<?
$handle=opendir('/home/txt/'); 
$i=0;
while ($file = readdir($handle)) { 
    if ($file != "." && $file != ".." && $file !="0") { 
        echo $file."<br>";
        $i++; 
    } 
}
closedir($handle); 
?>

if we have a file named 0 in dir "/home/txt/" and then we creat some other files, the files' list in html will not include files last created.
i think maybe readdir return 0 when it get file who's name equal 0.

yes, "0" evaluates to false so the loop is terminated

try 

while (""!=($file = readdir($handle))) 

instead, that will do

(bug closed until someone comes up with a filesystem 
where a filename may be all empty)
