Hi Amaury

It doesn't look like you're sending the cookie-file on the second curl_exec
- As a start, I'd add those specifications on the 2nd exec;
[---]
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);

DISCAIMER:
I've never used curl lib (as I'm stuck with WIN32) but I use curl.exe a lot,
so this should get you a little closer.

Hope This Helps.
