mais j'ai reçu un message d'erreur :
Fatal error: Call to undefined function pcntl_fork() in C:\xampp\htdocs\communication\nh.php on line 214


je vous merci d'avance

Bonjour,
CF la doc

Le support du contrôle des processus n'est pas activé par défaut en PHP. Vous devez compiler la version CLI ou CGI de PHP avec l'option de configuration --enable-pcntl pour activer le support de cette extension.

Il semble que l'extension ne soit pas activée dans ton cas.

bonjour hiba, enfin je travail sur le même fichier , et après quelque recherches ,j'ai finis par trouver que la fonction "pcntl_fork()" ne marche pas avec le php sous le WIN32 ,et fonctionne correctement sous Linux . b.courage.
