 New Comment:

The same problem occurs with Parallels Workstation under Windows 7, when using 
shared folders. DirectoryIterator is not iteratable using foreach.

Windows 7
Parallels Workstation v6
Linux Ubuntu 12.04.1-LTS

Any suggested workaround?

Hi Everyone,

I had the same problem on ubuntu (which is also debian based).
After installing the VirtualBox guest additions that are on the ISO that comes 
with VirtualBox instead of the guest additions bundled with debian/ubuntu 
solved the issue.

So you just have do install the guest additions on your VM and it should work 
fine.

The problem is reproducible with php5.3-201103170730

Please try using this snapshot:

  http://snaps.php.net/php5.3-latest.tar.gz
 
For Windows:

  http://windows.php.net/snapshots/

Works perfectly for me. "PHP version: 5.3.5-1" is none of our version numbers. 
MAybe your distribution has patched this somehow. Please test our version or 
talk to the distributor.

Description:
------------
Hello,

DirectoryIterator is iterable in a while but not in a foreach.

This bug is reproductible only on a vboxsf filesystem. I run this script on 
Debian sid hosted on Windows XP (NTFS formated hd).

I have no problem when I execute this script on Windows or on a virtual disk.

Test script:
---------------
<?php
function test_iterator($dirname) {
    $files = array();

    $dir = new DirectoryIterator($dirname);
    while($dir->valid()) {
        $files[] = (string)$dir->current();
        $dir->next();
    }
    return $files;
}

function test_iterator_bug($dirname) {
    $files = array();

    $dir = new DirectoryIterator($dirname);
    foreach($dir as $file) {
        $files[] = (string)$file;
    }
    return $files;
}

echo 'PHP version: ' . phpversion() . "\n\n";
$dirname = dirname(__FILE__);
foreach (array('iterator', 'iterator_bug') as $test_name) {
    echo "--- {$test_name} ---\n";
    $foo = "test_{$test_name}";
    var_dump($foo($dirname));
    echo "\n";
}


Expected result:
----------------
PHP version: 5.3.5-1

--- iterator ---
array(3) {
  [0]=>
  string(1) "."
  [1]=>
  string(2) ".."
  [2]=>
  string(9) "index.php"
}

--- iterator_bug ---
array(3) {
  [0]=>
  string(1) "."
  [1]=>
  string(2) ".."
  [2]=>
  string(9) "index.php"
}


Actual result:
--------------
PHP version: 5.3.5-1

--- iterator ---
array(3) {
  [0]=>
  string(1) "."
  [1]=>
  string(2) ".."
  [2]=>
  string(9) "index.php"
}

--- iterator_bug ---
array(0) {
}
