Voilà je voudrais uploadé un fichier texte sur un server web. 
Pour celà j'ai mis un script php sur le server le script marche si je passe par un formulaire. 
 
Mais si j'envoie la requette POST de client.c bin la le server ne répond pas alors que sur la une commande GET / je pe lire la réponse. 
 
Je pense donc que ma requette et mauvaise. Et aussi j'aimerais savoir se que ces que boundary. 
 
Merci 
 
Voici les 2 sources. 
 
 
 <?php 
 //up.php 
 
 $dossier = ''; 
 $fichier = basename($_FILES['file']['name']); 
 $taille = filesize($_FILES['file']['tmp_name']); 
 $extensions = array('.txt'); 
 $extension = strrchr($_FILES['file']['name'], '.'); 
 
 if(!in_array($extension, $extensions)) //Si l'extension n'est pas dans le tableau 
 { 
 £spaces£ £/spaces£$erreur = 'Just txt file!'; 
 } 
 
 if(!isset($erreur)) //S'il n'y a pas d'erreur, on upload 
 { 
 £spaces£ £/spaces£if(move_uploaded_file($_FILES['file']['tmp_name'], $dossier . $fichier)) //Si la fonction renvoie TRUE, c'est que ça a fonctionné... 
 £spaces£ £/spaces£{ 
 £spaces£ £/spaces£echo 'Upload OK!'; 
 £spaces£ £/spaces£} 
 £spaces£ £/spaces£else //Sinon (la fonction renvoie FALSE). 
 £spaces£ £/spaces£{

 else
