Il y a un probleme lorsque j'essaye d'installer, en SSH avec Putty

A priori, proc_open est désactivé sur ton hébergeur. Pour vérifier, tu peux afficher la configuration par :

Code:

echo ini_get('disable_functions');

Si popen, proc_open ou quelque chose du genre est dans la liste, tu es coincé. Adresse-toi à ton hébergeur directement.

Oui apres recuperation du fichier php.ini
Les fonctions phpinfo(), popen, proc_open(),, exec() ... et autre sont désactivées
et impossible de modifier le fichier sans être root

Une autre solution ? (pour installer paypal/rest-api-sdk-php
sur le serveur)
