How can I enable cURL for an installed Ubuntu LAMP stack?
From Install Curl Extension for PHP in Ubuntu:
sudo apt-get install php5-curl
After installing libcurl, you should restart the web server with one of the following commands,
sudo /etc/init.d/apache2 restart
or
sudo service apache2 restart
You only have to install the php5-curl library. You can do this by running
sudo apt-get install php5-curl
