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!
