What are the potential security risks of using XAMPP for testing IPN scripts?

One potential security risk of using XAMPP for testing IPN scripts is that it is not recommended for production use due to its default settings and configurations that may leave your system vulnerable to attacks. To mitigate this risk, it is advised to set up a separate, secure environment for testing IPN scripts, such as a virtual private server (VPS) or a dedicated testing server.

// Example PHP code snippet to securely test IPN scripts on a dedicated testing server
// Set up a dedicated testing server environment with proper security configurations
// Use secure coding practices and implement proper validation and sanitization of input data
// Regularly update and patch your server and scripts to address any security vulnerabilities
// Monitor and log all IPN transactions for any suspicious activity
