PHP i18N Library: Translate application texts loaded from XML files

This class uses two levels XML files to translate words,sentences, etc.
It can load one or more translation files at one time.

You can change the default $lang_folder and the default $locale to whatever you need in the class, but they are only used in the get_commun() function, wich is optionnal.

A function i18N_T() is provided to ease the use of the class.

In my case, the structure is :
module
    ->langages
        ->fr_FR.UTF-8
            ->XML file(s)
        ->en_GB.UTF-8
            ->XML file(s)

The two XML structures are :

<?xml version="1.0" encoding="UTF-8"?>
<dictionnaire>
	<module type="commun">
		<couple>
			<source>Original word OR sentence</source>
			<cible>Translated word OR sentence</cible>
		</couple>
        </modules>
</dictionnaire>

and

<?xml version="1.0" encoding="UTF-8"?>
<dictionnaire>
	<module type="commun">
		<couple>
			<source>Publier, gérer et lire des fanfics, des histoires originales, des poèmes<br />et autres textes en ligne</source>
			<cible>
                                <couple>
					<source type="==1">Il y a %d objet.</source>
					<cible>There is %d object.</cible>
				</couple>
				<couple>
					<source type=">1">Il y a %d objets.</source>
					<cible>There are %s objects.</cible>
				</couple>
			</cible>
		</couple>
        </modules>
</dictionnaire>

Of course, you can mixe them.

The name of the module can be empty. It has no importance in this version, but could have in a further one.
Of course, you can have several modules and several couples in a dictionary.

How to call a dictionary (case french to english) :

include 'class.dictionnaires.php';
$dictionnaire = new dictionnaire($_SESSION['locale']);
$dictionnaire->get_fichiers(array(__DIR__.'/langages/'.$_SESSION['locale'].'/commun.xml'));

How to use it :

print i18N_T("Un objet");
-> prints : An object
Otherwise prints "Un objet" if there is no translation.

You can use more than one dictionary at a time :

include 'class.dictionnaires.php';
$dictionnaire1 = new dictionnaire($_SESSION['locale']);
$dictionnaire2 = new dictionnaire('en_US.UTF-8');
print i18N_T("Consulter tous les articles",null,$dictionnaire1);

You can use comparison for plural :

printf("%d %s",7,i18N_T("nbevenements",'>0'));
