How does SSL encryption impact the performance of a PHP website or application?

SSL encryption can impact the performance of a PHP website or application by adding overhead due to the encryption and decryption processes. This can result in slower response times and increased server load. To mitigate this impact, you can optimize your SSL configuration, use a content delivery network (CDN) with SSL acceleration, or implement caching mechanisms. 

// Example of implementing SSL acceleration using a CDN
if ($_SERVER['HTTPS'] != 'on') {
    header('Location: https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']);
    exit();
}
