Affichage de tout un bloc dans un template

Bonjour, je suis en train de réaliser un site Internet en PHP et je suis en train d'essayer la méthode des templates.

Un petit tour d'horizon de ce que j'ai réaliser pour l'instant.
J'ai récuperer une classe template.inc sur le net :

Code :

?>

J'ai ensuite intégrer dans un fichier template.html un espace reservé pour mes informations :

Code :

<div id="centre">
{centre}
</div>

J'ai ensuite créer un script php avec le contenu à mettre dans cet espace

Code :

<?
include(dirname(__FILE__).'/contenu/include/connexion.php');
// Assignation du bloc simple {NBRFRUITS} par sa valeur
$template->set_var("centre", $contenu);
// Traitement de la page entière
$template->parse("parse", "index" );
// Suppression des blocs simples sans valeur ou boucles non utilisés (ici aucun)
// Affichage de la page
$template->p("parse" );
?>

Mon probleme est que je ne sais pas comment intégrer tout le contenu que je souhaite afficé dans une meme variable que j'ai appellé ici $contenu. Je ne sais pas vraiment comment je dois procéder!!

Si mon probleme n'est pas clair, n'hesitez pas a m'en faire la remarque

Merci par avance, Karine

excuse moi j'y connais rien en template, donc dsl si ma réponse est à coté de la plaque, mais ce que tu demandes c'est comment mettre plusieurs données dans une seule variable? genre comme dans un tableau à plusieurs dimensions?
enfin je me dis que j'ai rien du comprendre sinon ca serait trop simple
