cURL in PHP is a PHP extension that allows you to execute or use URLs to send post HTTP requests or get data from the server. cURL simple works between the Client side to server side and server side to client-side data submit and receive.

To use cURL you need just need to pass the request method and header for the type of getting and receiving form data on the server side. We just need to define each request method like getting & POST.

If the request is authenticated you can also pass tokens or API keys in the header to access server-side data using cURL in the PHP application.
