New Comment:
I encoutered the same error, my problem was not a bug, but a bad
relative path error inside the script function is_dir(), maybe it can
help someone having the same problem.
I am using Linux.
With the folowing structure
/var/www/vhosts/test.com/httpdocs/images/items_images/file1.jpg
/var/www/vhosts/test.com/httpdocs/images/items_images/temp
/* The folder "temp" will show as directory with the following script:
*/
$full_path = "/var/www/vhosts/test.com/httpdocs/images/items_images";
if ($handle = opendir("$full_path")) {
while (false !== ($file = readdir($handle))) {
if(is_dir($full_path."/".$file)) continue;
else echo $file;
}
}
/* The folder "temp" will show as a file with the following script: */
$full_path = "/var/www/vhosts/test.com/httpdocs/images/items_images";
if ($handle = opendir("$full_path")) {
while (false !== ($file = readdir($handle))) {
if(is_dir($file)) continue;
else echo $file;
}
}

<code>
// this script runs under user www-data
// Apache/2.2.3 (Debian)
// PHP/5.2.0-8+etch11
...
echo "\$dirName is $dirName<br>\n";
$FullDirname = realpath( $dirName );
echo "\$FullDirname is $FullDirname<br>\n";
if (!is_dir( $FullDirname )) {
// as the directory is there this should never
// be displayed!
echo "$FullDirname is not a directory<br>\n";
}
</code>
output:
$dirName is mswbt_A6565897X3B91B
$FullDirname is /var/www/V3.46-pre03/source/mswbt_A6565897X3B91B
/var/www/V3.46-pre03/source/mswbt_A6565897X3B91B is not a directory
this clearly shows that the directory is there
$ ls -als /var/www/V3.46-pre03/source/

Msg to tony2...@php.net:
Please do not try to run this code on your machine. You will most
probably *not* have this directory structure and the is_dir() function
call would succeed on your machine as returning FALSE would be correct
then!
I hope this can help a bit to solve the problem.

I having the same problem.
OS: FreeBSD 6.2
PHP: 5.1.2
Server: Apache 2.2
Mount a windows share.
Run the following on the windows share:
$d = dir("Path/to/windows/share");
while (false !== ($entry = $d->read())) {
echo "Entry: $entry<br>\n";
var_dump(is_dir($entry));
echo "<br>";
}
All sub-directories on the windows share return:
Entry: Sub_Dir_1
bool(false)
Entry: Sub_Dir_2
bool(false)

The problem seems affecting only the temporary directory's
subdirectories; please fix this bug because it is causing a lot of weird
effects on scripts which verify paths existance and eventually create
them.
I am using PHP 5.2.0 and running this script:
<?php
// bug #39198 testcase, see http://bugs.php.net/bug.php?id=39198
// @author legolas558
if ( !function_exists('sys_get_temp_dir') ) {
// Based on http://www.phpit.net/
// article/creating-zip-tar-archives-dynamically-php/2/
function sys_get_temp_dir() {
// Try to get from environment variable
if ( !empty($_ENV['TMP']) )
return realpath( $_ENV['TMP'] );
else if ( !empty($_ENV['TMPDIR']) )
return realpath( $_ENV['TMPDIR'] );
else if ( !empty($_ENV['TEMP']) )
return realpath( $_ENV['TEMP'] );
// Detect by creating a temporary file
else {
// Try to use system's temporary directory
// as random name shouldn't exist
$temp_file = tempnam( md5(uniqid(rand(), TRUE)), '' );
if ($temp_file) {
$d_temp = realpath( dirname($temp_file) );
unlink( $temp_file );
return $d_temp;
} else
return FALSE;
}
}
}
$d_temp= sys_get_temp_dir();
if ($d_temp===false)
die('Cannot retrieve temporary path');
$d_temp = str_replace('\\','/', $d_temp);
if ($d_temp[strlen($d_temp)-1]!='/')
$d_temp .= '/';
// now $d_temp contains a correctly formatted path e.g.
C:/Windows/TEMP/
$my_temp_subdir = $d_temp.'39198_exists';
if (@rmdir($my_temp_subdir))
echo "I just removed a previous <strong>$my_temp_subdir</strong>
folder, now ";
// create a directory under the temporary path
if (!mkdir($my_temp_subdir))
die("I could not create <strong>$my_temp_subdir</strong>");
else
echo "<strong>$my_temp_subdir</strong> was created ";
// use here temp_is_dir() to see how the script should work instead
$b = is_dir($my_temp_subdir);
if (!$b)
echo "but the folder is not a dir (through is_dir())!";
else
echo "and is recognized as a dir (through is_dir())";
// workaround function
function temp_is_dir($dir) {
// check directory existance under temp folder (tested on Windows)
// see bug #31918 http://bugs.php.net/bug.php?id=39198
// by legolas558
if (!...@mkdir($dir))
return true;
rmdir($dir);
return false;
}
?>
I get this talkative output:
[code]
C:/WINDOWS/Temp/39198_exists was created but the folder is not a dir
(through is_dir())!
[/code]
But the correct talkative output would be instead:
[code]
C:/WINDOWS/Temp/39198_exists was created and is recognized as a dir
(through is_dir())
[/code]
Note that using the workaround function "temp_is_dir()" in place of
"is_dir()" the correct output would be returned instead. Please ask me
more if necessary.
