Chat php/ajax simple et compact

Contenu du snippet

Voici un petit script de chat php/ajax, j'ai 15 ans c'est la première source que je dépose ...

c'est un petit script de base pour les débutants, le script Ajax n'est pas très compliqué, je me suis aidé de ce site : http://www.xul.fr/xml-ajax.html pour l'Ajax car je n'y connaissait rien.
L'originalité est dans le faite que le script ne nécessite aucune base de donnée ni aucun fichier texte puisqu'il s'auto-modifie.

Le Script possédé désormais une gestion des utilisateurs, et un tout nouveau design.
Pour connecter un utilisateur, il suffit, soit de se rendre sur la page et la on vous demandera de choisir un pseudo, soit d'appeler la page et de faire passer le pseudo de l'utilisateur par l'url (PAGE.php?login=PSEUDO , les caractères majuscule sont à modifier.)

Ps: Je n'ai pas le temps de mettre les explications de mon script, je le ferais ce soir ou demain ...

merci de dire ce que vous en pensez et de mettre une note !
