For many things I work on cURL is needed.
I often forget exactly how to do it.
If it helps you, that is great.
But, these steps are mostly for me:
sudo apt-get install curl php5-curl
sudo vi /etc/php5/apache2/php.ini
add the following to the extensions section--
extension=curl.so
PgDn will allow you to navigate to the bottom of the file quickly enough
i will allow you to enter new data
Esc will exit data entry mode
When you are out of data entry mode, dd will delete a whole line if you made a mistake
save by typing-- :!w
exit by typing-- :!q
sudo /etc/init.d/apache2 restart
