It's basically a library within php that you can use to get remote information from other sites.

 

In short cURL is a unix command to simulate the browser or to download files. The cURL in php is the module of the library that is like a wrapper around that command.

 

is this something related to file_get_contents() in php can i make proxy site using cURL
