It is a command line tool for sending and getting files using URL syntax.
cURL allows communicating with other servers using HTTP, FTP, Telnet, and more.
Approach:
We are going to fetch JSON data from one of free website, which gives JSON data for testing i.e. reqres.in
First, we initialize curl using curl_init() method.
Sending GET request to reqres.in server using curl_setopt() method with CURLOPT_URL to get json data.
After that, we have to tell curl to store json data in a variable instead of dumping on screen. This is done by using CURLOPT_RETURNTRANSFER parameter in curl_setopt() function.
Execute curl using curl_exec() method.
At last, close the curl using curl_close() method.
