Php gettext directory structure in different environments

I use gettext for internationalization for my php files. I have two servers; sandbox server and release server. in a sandbox server, a directory like locale/LC_MESSAGES/en does not work, and instead I have to use locale/LC_MESSAGES/en_GB . But with "en_GB" it does not work on my production server, and "ru" works fine. for some languages, such as Portuguese, I have pt_PT and pt_BR (Brazilian Portuguese). Therefore, I prefer to use the structure "A_B".

I have no idea how gettext detects these folders. Is there a standard way to use the same folder structure?

If you use your code on Linux, gettext only works with locales already installed on the OS. This means that if you set the language standard to en_GB , then if only the installed language standard is en_GB.utf8 or en_US , then you will not receive translations.

Try this in both environments and compare the results:

 locale -a

It gives you a list of all installed locales:

 en_US en_US.ISO8859-1 en_US.ISO8859-15 en_US.US-ASCII en_GB en_GB.utf8 de_DE de_DE.utf8 C POSIX

Now you need to make sure that both environments have the same locales; If you need en_US.utf8 , en_AU and en_AU.utf8 , you can create missing locales based on the existing one (read the localedef manpages for details):

 sudo localedef -c -i en_US -f UTF-8 en_US.utf8 sudo localedef -c -i en_GB -f UTF-8 en_AU sudo localedef -c -i en_GB -f UTF-8 en_AU.utf8

In addition, it follows that the common best practice for using gettext in PHP is:

 <?php // Set language to German putenv('LC_ALL=de_DE.utf8'); setlocale(LC_ALL, 'de_DE.utf8'); // Specify location of translation tables bindtextdomain("myPHPApp", "./locale"); // Choose domain textdomain("myPHPApp"); // Translation is looking for in ./locale/de_DE.utf8/LC_MESSAGES/myPHPApp.mo now // Print a test message echo gettext("Welcome to My PHP Application"); // Or use the alias _() for gettext() echo _("Have a nice day"); ?>

Although you can simply drop the encoding and just de_DE , it’s good practice to type characters in a locale, as in some specific cases you may need to support content in character sets other than Unicode. See below

 <?php // Set language to German written in Latin-1 putenv('LC_ALL=de_DE.ISO8859-1'); setlocale(LC_ALL, 'de_DE.ISO8859-1'); ?>
