What protocols should be considered when using CURL in PHP for data transmission?

When using CURL in PHP for data transmission, it is important to consider the protocols that are supported by the remote server. Some common protocols to consider are HTTP, HTTPS, FTP, and FTPS. By specifying the appropriate protocol in the CURL options, you can ensure that the data is transmitted securely and efficiently. 

// Specify the protocol to be used for data transmission
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://example.com/data');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_PROTOCOLS, CURLPROTO_HTTPS); // Specify HTTPS protocol
$response = curl_exec($ch);
curl_close($ch);

// Process the response data
echo $response;
