<?php
// Prerequisite:
// 1. Copy some .mo file from your system to /tmp/fr_FR/LC_MESSAGES/run.mo
// 2. ./configure --with-gettext GetText Support: enabled
setlocale(LC_MESSAGES,'fr_FR');
bindtextdomain('run','/tmp');
textdomain('run');
echo "\n";
echo gettext('AZERTY'); // The file run.mo must exists but the string not
echo "\n";
