There's some tutorials out there for gettext (w/ Poedit)... unfortunately, it's mostly for a UNIX environment. And even more unfortunate is that I am running my WAMP server on Windows XP (but I am developing for a UNIX environment) and none of the tutorials can get gettext working properly for me. From the man page (http://us3.php.net/manual/en/book.gettext.php), it appears that it's a different process on a Windows environment. I've tried out some of the solutions in the comments but I still can't get it to work! Please, I've spent many hours on this, hopefully someone can point me in the right direction to get this thing to work! (and I'm sure there are others out there who share my frustration). So far with my setup, I'm only getting output "Hello World!" whereas I should be getting the translated string.

Here is my setup/code so far:

<?php
// test.php
if (!defined('LC_MESSAGES')) {
    define('LC_MESSAGES', 6);

}
$locale = "deu_DEU"; // apparently the locales are different on a WINDOWS platform

putenv("LC_ALL=$locale");
setlocale(LC_ALL, $locale);
bindtextdomain("greetings", ".\locale");
textdomain("greetings");


echo _("Hello World"); 

?>

Folder structure

root:     C:\Program Files\WampServer 2\www
test.php: C:\Program Files\WampServer 2\www\site
.po:      C:\Program Files\WampServer 2\www\site\locale\deu_DEU\LC_MESSAGES\greetings.po
.mo:      C:\Program Files\WampServer 2\www\site\locale\deu_DEU\LC_MESSAGES\greetings.mo

Please advise! Thanks for your time :)
