Many times we come across web applications which are written in PHP and require curl extension. PHP curl functions can used through use of libcurl. The libcurl was create by Daniel Sternberg. With the help of libcurl you can connect and communicate with webserver using different protocols. To install curl library on your Ubuntu computer, you need to have LAMP (Linux apache mysql php) set up ready. Once you have Lamp setup ready just type in following command in terminal to install curl library,

sudo apt-get install curl libcurl3 libcurl3-dev php5-curl

After installing libcurl you should restart the web server with following command,

sudo /etc/init.d/apache2 restart

If you don’t have LAMP functionality already installed, then please click on the following link to find out how install LAMP on Ubuntu Linux,
