Merci :)
Je veux aussi enlever l'erreur "Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in C:\Wamp\www\RoWiki\index.php on line 140".

PS : Corrigez aussi si il y a des optimisations à faire.

J'ai modifié un peu le code. Mais il reste des optimisations à faire et toujours l'erreur :
