PHP gettext - basic help needed

Question

I'm trying to get a very basic setup of gettext working on my local server.

I've installed it and I can see it available when I run phpinfo().

My test php file is:

<?php
$language = 'fr';
putenv("LANG=$language"); 
setlocale(LC_ALL, $language);

// Set the text domain as 'messages'
$domain = 'messages';
bindtextdomain($domain, "/Tom/Web/locale/"); 
textdomain($domain);

echo gettext("A string to be translated would go here");
?>

In /Tom/Web/locale I have two folders en and fr

(this web root is /Tom/Web/)

Within each of those folders I have LC_MESSAGES and within that I have messages.po & messages.mo

Within the message.po file in fr/LC_MESSAGES I have :

# SOME DESCRIPTIVE TITLE.
# Copyright (C) YEAR THE PACKAGE'S COPYRIGHT HOLDER
# This file is distributed under the same license as the PACKAGE package.
# FIRST AUTHOR <EMAIL@ADDRESS>, YEAR.
#
msgid ""
msgstr ""

"Last-Translator: \n"
"Language-Team: \n"
"X-Generator: Poedit 2.0.3\n"
"X-Poedit-SourceCharset: UTF-8\n"

#: test.php:12
msgid "A string to be translated would go here"
msgstr "Une chaîne à traduire irait ici"

Yet when I open the tstp.php page in my browser I get the english text not the French.

What have I done wrong ?

Thanks.

Answer 1

The language and directory should be fr_FR. It's a long time since I used gettext(), but I think you have the specify the country and language. (eg en_GB and en_US are different versions of English)
