What are the potential security risks of accessing and displaying PHP code from a remote server?

Accessing and displaying PHP code from a remote server can pose security risks such as exposing sensitive information, allowing for remote code execution, and potential injection attacks. To mitigate these risks, it is recommended to use proper authentication and authorization mechanisms, sanitize input data, and avoid displaying raw PHP code to users. 

// Example of securely accessing and displaying PHP code from a remote server
$url = 'https://example.com/remote_php_code.php';

// Fetch the remote PHP code using cURL
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);

// Display the sanitized PHP code to the user
echo htmlentities($response);
