Are there any specific PHP extensions or libraries that need to be installed to use the CURLFile class?

To use the CURLFile class in PHP, you need to ensure that the cURL extension is enabled in your PHP installation. This extension is required for handling file uploads with cURL. You can check if the cURL extension is enabled by running `phpinfo()` in your code or checking your php.ini file. 

// Check if cURL extension is enabled
if (!function_exists('curl_init')) {
    die('cURL extension is not enabled. Please enable it to use the CURLFile class.');
}
