The second message is about curl, as I suspected, it's not working. Could I
add to a precompiled installation of php?
I got it!
--> I fixed the params bug: just putting: *public function initialize(
$name, $url/*, $na, $nb = false*/ ) {*
--> I added curl support by doing:
sudo apt-get install *curl* libcurl3 libcurl3-dev php5-*curl
* sudo /etc/init.d/apache2 restart
Now the code work fine when uploading from url. I cannot still upload from
file, but think I'll fix soon. Thank you a lot for your help!
