Gettext示例在Windows 7上不起作用-XAMPP

我拥有PHP 5.6.8和启用了gettext的最新XAMPP(3.2.1).我正在尝试使用我在互联网上找到的示例来使gettext()在那里工作: https://github.com/leftnode/gettext-example ，但不起作用.

I have the latest XAMPP (3.2.1) with PHP 5.6.8 and gettext enabled. I'm trying to get gettext() working there using a sample I've found on the internet: https://github.com/leftnode/gettext-example , but it is not working.

我尝试过的其他代码(translation.php):

Other code I've tried (translation.php):

<?php
  session_start();

  $textdomain = "messages";
  $lang = "de_DE";

  echo(putenv("LC_ALL=".$lang)."<br>"); // outputs 1
  setlocale(LC_ALL, $lang);
  echo(bindtextdomain($textdomain, "locale")."<br>"); // successfully outputs the correct path to locale
  textdomain($textdomain);

  echo ((function_exists("_") && function_exists("gettext"))?"gettext loaded\n<br>":""); // outputs gettext loaded

  $name = "Vic";
  printf(_("Hello, %s, it is nice to see you today.\n"), $name); // outputs original english
?>

翻译文件-使用Poedit 1.8.1(messages.po)编译

还有什么我可以尝试使gettext工作的?

What else can I try to make the gettext working?
