Are there best practices for integrating third-party PHP scripts, like the one found for sending greeting cards, into a website?

When integrating third-party PHP scripts into a website, it is important to ensure that the script is secure, well-documented, and compatible with your website's environment. It is also recommended to test the script thoroughly before deploying it to production to avoid any potential issues. Additionally, it is a good practice to keep the script updated to the latest version to ensure optimal performance and security.

<?php
// Include the third-party PHP script for sending greeting cards
include 'send_greeting_card.php';

// Call the function from the script to send a greeting card
send_greeting_card('recipient@example.com', 'Happy Birthday!');
?>
