Comment by: mark_ford_uk at yahoo dot co dot uk
Reported By: itamarc at rogers dot com
Status: Bogus
Bug Type: Directory function related
Operating System: windows xp
PHP Version: 4.3.1
New Comment:
(currently using php4.2.2)
I too have discovered directories are not always recognised,. However,
I have found they are correctly recognised provided I ensure the path
has a '/' on the end.
This bug appears to be widely reported and to my knowledge has not been
fixed even in recent versions. Can someone please investigate?
Thanks.

Sorry, but your problem does not imply a bug in PHP itself. For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system
is not the
appropriate forum for asking support questions.
Thank you for your interest in PHP.
Next time: make the script shorter, please! We don't need the size
stuff.
IIC - when the first entry is a directory it will always fail, because
you only change dirs after you read a file.
Make the test:
if(!is_dir("$dir/$entry"))
and you'll see it'll always work.

let's see. using apache2 on win xp pro
<?

$temp = $_GET['directory'];
$d = dir("d:/inetpub/wwwroot/$temp");
$old = $_GET['old'];

$old = "";

$totaldirsize = 0;
$mark = 1;

Yes, you said that already.
Let's see the script you used which exposes this bug.
For example - this works for me, using 4.3.1 on Windows 2k with
apache:
<?php
header('Content-Type: text/plain');
$dir = opendir('.');
while($entry = readdir($dir))
{
if(is_dir($entry))
echo "$entry is a dir\n";
else
echo "$entry is NOT a dir\n";
}
?>

the is_dir is supposed to come back true if reading a directory and
false if not. it doesn't. it always comes back false.
if used as (not)!is_dir then it works right most of the time but still
give the wrong answer for some directories.
