Bonjour,

Excusez-moi, je ne savais pas trop où poster mon message, je le fais donc ici. Je dois développer une interface web pour gérer des switchs. Je communique donc en telnet via php avec mon switch. J'ai réussi à procéder à l'affichage de données. Mais, lorsque je veux effectuer une commande me permettant de modifier la configuration du switch (ici, les vlans), problème : la page tourne en boucle et n'affiche rien. Je viens donc demander de l'aide, en espérant avoir été clair..


Le code de la fonction :
