Are there any best practices or recommended approaches for integrating PHP with external servers or controllers?

When integrating PHP with external servers or controllers, it is recommended to use secure protocols such as HTTPS to ensure data privacy and integrity. Additionally, implementing proper error handling and validation checks can help prevent security vulnerabilities and data breaches. It is also advisable to keep sensitive information, such as API keys, secure by storing them in environment variables or using encryption techniques. 

// Example code snippet for integrating PHP with an external server using cURL with HTTPS
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://example.com/api');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Set any necessary headers or authentication tokens
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Authorization: Bearer YOUR_API_KEY'
));

$response = curl_exec($ch);
if($response === false){
    // Handle error
    echo 'cURL error: ' . curl_error($ch);
} else {
    // Process the response data
    echo $response;
}

curl_close($ch);
