Question

I’m using the following code to loop through a directory to print out the names of the files. However, not all of the files are displayed. I have tried using clearstatcache with no effect.

    $str = '';     $ignore = array('.', '..');      $dh = @opendir( $path );     if ($dh === FALSE)     {         // error     }      $file = readdir( $dh );     while( $file !== FALSE )     {         if (in_array($file, $ignore, TRUE)) { break; }         $str .= $file.'\n';         $file = readdir( $dh );     } 

Here’s the contents of the directory right now:

root.auth  test1.auth  test2.auth  test3.auth  test5.auth 

However, test5.auth does not appear. If I rename it to test4.auth it does not appear. If I rename it to test6.auth it does appear. This is reliable behaviour – I can rename it several times and it still won’t show up unless I rename it to test6.auth.

What on earth could be happening?

I’m running Arch Linux (kernel 2.6.26-ARCH) with PHP Version 5.2.6 and Apache/2.2.9 with Suhosin-Patch. My filesystem is ext3 and I’m running fam 2.6.10.

Your break keywords messes up your code:
Your loop very likely first encounters the ‘.’ directory and than breaks out of your while loop.

try replacing it with a continue and you should be fine.
