What are the potential security risks of including files from another server in PHP?

Including files from another server in PHP can pose security risks such as remote code execution, data leakage, and potential injection attacks. To mitigate these risks, it is recommended to validate and sanitize input data, use secure communication protocols like HTTPS, and restrict access to sensitive files on the server. 

// Example of including a file from another server securely
$url = 'https://example.com/file.php';
$response = file_get_contents($url);

// Validate and sanitize the response before including it
if ($response !== false) {
    // Process the response content securely
    include($response);
}
