JayBachatero:
Software: phpBB
Version: 3.0

It's finally here.  Spent the whole day working on it and managed to get a beta out.  The converter is still in beta and some things are missing.  If you have suggestions for other things to convert just post them :) .  Here is a list of what is converted.

Converts
* Members
* Ranks
* Groups
* Categories
* Boards
* Topics
* Posts
* Attachments
* Personal Messages
* PollsDoes Not Convert
* Permissions (This might not be supported at all so please check permissions before making the board live.  Everything will be admin only for board access.)
* Redirection Boards (I want to add support for the redirection boards mod.)
* Avatars
* Profile Fields (I want to look into this and see if I can make them SMF compatible.  You would just need to make the template changes.)
* Basic Settings (Convert some of the basic forum settings. (site name, max post length, etc)
* Smileys
Password Support
phpBB has their own custom password hash so you need to edit Sources/LogInOut.php from the SMF folder to add support for password conversion. Alternatively, you can used the attached phpBB3_Login_Fix.tgz modification (attached below) via Package Manager.


--- Code: (find) ---            // Snitz style - SHA-256.  Technically, this is a downgrade, but most PHP configurations don't support sha256 anyway.
            if (strlen($user_settings['passwd']) == 64 && function_exists('mhash') && defined('MHASH_SHA256'))
                $other_passwords[] = bin2hex(mhash(MHASH_SHA256, $_REQUEST['passwrd']));

--- End code ---


--- Code: (add after) ---            // phpBB3 users new hashing.
            $other_passwords[] = phpBB3_password_check($_REQUEST['passwrd'], $user_settings['passwd']);

--- End code ---


--- Code: (find) ---?>

--- End code ---


--- Code: (add before) ---function phpBB3_password_check($passwd, $passwd_hash)
{
    // Too long or too short?
    if (strlen($passwd_hash) != 34)
        return;

    // Range of characters allowed.
    $range = './0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz';

    // Tests
    $strpos = strpos($range, $passwd_hash[3]);
    $count = 1 << $strpos;
    $count2 = $count;
$salt = substr($passwd_hash, 4, 8);

    // Things are done differently for PHP 5.
    if (@version_compare(PHP_VERSION, '5') == 1)
    {
        $hash = md5($salt . $passwd, true);
        for (; $count != 0; --$count)
            $hash = md5($hash . $passwd, true);;
    }
    else
    {
        $hash = pack('H*', md5($salt . $passwd));
        for (; $count != 0; --$count)
            $hash = pack('H*', md5($hash . $passwd));
    }

    $output = substr($passwd_hash, 0, 12);
    $i = 0;
    while ($i < 16)
    {
        $value = ord($hash[$i++]);
        $output .= $range[$value & 0x3f];

        if ($i < 16)
            $value |= ord($hash[$i]) << 8;

        $output .= $range[($value >> 6) & 0x3f];

        if ($i++ >= 16)
            break;

        if ($i < 16)
            $value |= ord($hash[$i]) << 16;

        $output .= $range[($value >> 12) & 0x3f];

        if ($i++ >= 16)
            break;

        $output .= $range[($value >> 18) & 0x3f];
    }

    // Return now.
    return $output;
}

--- End code ---

Notes:
- Set SMF to UTF-8 mode since phpBB3 is set to UTF-8 by default.

Aaron:
Great job Jay! I'm sure you've just made a lot of people happy. :)

codenaught:
Awesome Jay! :D I'll give it a test run a little later.

Augh:
Thank You Jay :)

All working good now...

JayBachatero:
Augh can you check and make sure that entities where converter correctly?  phpBB uses utf8_bin for text fields so hopefully everything transfers correctly.

Another thing that I just remembered.  phpBB has support for sub categories.  SMF does support this so sub categories will be set as regular categories with the boards on the main page.
