ubuntu下为php设置gettext

Question

我尝试了什么：

1. sudo apt-get install php-gettext
2. sudo apt-get install gettext
3. sudo apt-get install locales

我的翻译文件（*.mo、*.po）在/usr/local/php/include/myapp/i18n/locale/ 下，例如 /usr/local/php/include/myapp/i18n/locale/da_DK/LC_MESSAGES/generic.mo

我已经把 /etc/php5/conf.d/gettext.ini

extension=gettext.so

apache2 restart 给了我这个错误：

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626/gettext.so' - /usr/lib/php5/20090626/gettext.so: cannot open shared object file: No such file or directory in Unknown on line 0

我做错了什么？据我所知，这是在 linux 下安装扩展的标准方法。这在我的本地系统上运行良好，但在亚马逊实例上却不行。

php --version PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626/gettext.so' - /usr/lib/php5/20090626/gettext.so: cannot open shared object file: No such file or directory in Unknown on line 0 PHP 5.3.10-1ubuntu3.10 with Suhosin-Patch (cli) (built: Feb 28 2014 23:14:25) Copyright (c) 1997-2012 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2012 Zend Technologies

请指导我在 ubuntu 上设置这个扩展。

所以这个谜团被优秀的SOQ解决了

php.net 上 gettext 的 comment 之一说：

Warning for Linux (Ubuntu) users!  Your system will *only* support the locales installed on your OS, in the *exact* format given by your OS.  (See also the PHP setlocale man page.)  To get a list of them, enter locale -a, which will give you something like this:

C
en_US.utf8
ja_JP.utf8
POSIX

So this machine only has English and Japanese!  To add eg. Finnish, install the package:

sudo apt-get install language-pack-fi-base

Rerun locale -a, and "fi_FI.utf8" should appear.  Make sure you're using the same name in your PHP code:

setlocale(LC_ALL, "fi_FI.utf8");

Adjust your po paths so that they match, e.g. "./locale/fi_FI.utf8/LC_MESSAGES/messages.po".

Now restart Apache, and it should finally work.  Figuring this out took quite a while...

我的问题完全按照以下步骤解决：

1. sudo apt-get install language-pack-da-base（丹麦语）
2. locale -a（确认已加载 da_DK 语言环境）

3. mv da_DK da_DK.utf8（重命名语言环境目录） bind_textdomain_codeset('messages', 'UTF8');

   对我来说，其中一个调试点是 setlocale(LC_ALL, 'da_DK.utf8'); 对于无效/不存在的语言环境返回 false

gettext.so 扩展怎么样：

我通过apt-get得到的php安装似乎在编译时添加了扩展 我们可以查看 gettext 是否是编译模块，例如 php -m |grep gettext ，这似乎是真的！ 我不需要gettext.ini，只有编译PHP时才需要--with-gettext=shared，这里不是这样。
