PHP gettext translation is not working

Question

I need to translate my site to Tamil. This is my code:

$locale = "ta_IN";

putenv("LANG=".$locale);
setlocale(LC_ALL, $locale);

$domain = "ta_IN";
echo bindtextdomain($domain, "Locale");
bind_textdomain_codeset($domain, 'UTF-8');

textdomain($domain);

echo  _("Username");

And I have create .mo and .po files for the word Username and which is in the /var/www/tamil/Locale/ta_IN/LC_MESSAGES/ta_IN.mo and ta_IN.po , but it is not translating my site.

I have these questions and their accepted answers, but the solutions did not work for me:

• PHP - GetText not working
• How to debug gettext not working in PHP?
• Gettext not working, no error messages, using php 5.3

如果要在控制台（PHP-CLI）上而不是在Web服务器上测试gettext，则也必须重置LANGUAGE环境变量。

putenv("LANGUAGE=");
