Comment envoyer de l'argent paypal à l'aide de php

J'ai été à la recherche pour le même problème, voici ce qu'est de travailler pour moi.
Testé dans 'bac à sable' de mode et l'utilisation de la NVP (au lieu du SAVON).
Votre serveur doit supporter CURL, afin de vérifier l'utilisation:

<?php
echo 'curl extension/module loaded/installed: ';
echo ( !extension_loaded('curl')) ? 'no' : 'yes';
echo "<br />\n";
phpinfo(INFO_MODULES); //just to be sure
?>

Si n'est pas chargé ou installé demandez à votre hostmaster ou obtenez-le ici, sinon, aller de l'avant:
