What are some of basic steps involved while using cURL?

Some of the basic steps involved in using cURL are:

• curl_init: It is used to initialize the session and also return a cURL handle that has been passed onto other cURL commands.
• curl_opt: This function can be used multiple times in order to specify what exactly the user expects the library to perform.
• curl_exec: This function is used to execute a cURL session that has been commanded by the user.
• curl_close: This function is used to close the session once the desired function has been performed as directed by the user.
