Probleme texte phpfreechat

Visiblement, tu n'as pas lu entièrement le lien que je t'ai donné :
https://codes-sources.commentcamarche.net/faq/11288-les-balises-de-code

Tu n'as pas indiqué le LANGAGE dans les balises de code.... ce qui aurait rendu ton code plus lisible sur le forum !

Pour finir, le code que tu nous montres n'a aucun intéret....
le code du chat étant généré via la class contenue dans le fichier phpfreechat.class.php

Ce qui me laisse penser que tu n'as pas écrit ce code... mais téléchargé quelque part.
Je t'invite donc à contacter le développeur de ce script

merci pour la réponse
Oui c'est un script dispo sur le web phpfreechat
Malheureusement il est très ancien et le développeur n'est plus joignable

Ben montre le code de la class au moins...

La version PHP qui tourne sur le serveur... vu que c'est lui qui exécute le code....
Si tu ne sais pas, tu peux créer un fichier à la racine de ton site et y mettre le code

<?php 
phpinfo();
?>

https://www.php.net/manual/fr/function.phpinfo.php


Ensuite tu affiches la page... et tu y cherches la version de php.

vous avez trouvé! version 5.6 ça fonctionne et pas en7.4
qu'est ce que je risque a le laisser en 5. 6?

Le 7 est plus performant. Donc ne touche à rien

ok
mais mon script ne tourne pas!
existe t'il un logiciel qui changerait le code du script en 7.4?
