What are best practices for troubleshooting PHP errors related to unknown functions like curl_init()?

When encountering PHP errors related to unknown functions like curl_init(), it is likely that the cURL extension is not enabled in your PHP configuration.

    echo "cURL extension is not enabled. Please enable it in your PHP configuration.";
    exit;
}
