What are some best practices for securely integrating external systems, such as a Minecraft server, with a PHP-based application?

When integrating external systems like a Minecraft server with a PHP-based application, it is important to prioritize security to prevent unauthorized access or attacks. One best practice is to use authentication mechanisms such as API keys or OAuth to verify the identity of the external system before allowing communication with the PHP application. Additionally, implementing input validation and sanitization can help prevent injection attacks and ensure the integrity of the data being exchanged between the systems. 

// Example code snippet for securely integrating an external system with a PHP application using API keys for authentication

$apiKey = 'your_api_key';

// Verify the API key provided by the external system
if ($_GET['api_key'] !== $apiKey) {
    http_response_code(401);
    exit('Unauthorized');
}

// Proceed with processing the request from the external system
// Your code logic here
