gettext Extension

gettext is a library that provides features to translate messages for the users. It includes the famous gettext() function, and its alias _() (underscore).

It is based on the locale system, and the .mo files.

<?php

    // example from the PHP manual: https://www.php.net/manual/en/function.gettext.php
    // Set language to German
    putenv('LC_ALL=de_DE');
    setlocale(LC_ALL, 'de_DE');

    // Specify location of translation tables
    bindtextdomain("myPHPApp", "./locale");

    // Choose domain
    textdomain("myPHPApp");

    // Translation is looking for in ./locale/de_DE/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)";

?>
