Early Hints

FrankenPHP natively supports the 103 Early Hints status code. Using Early Hints can improve the load time of your web pages by 30%.

  1. <?php
  3. header('Link: </style.css>; rel=preload; as=style');
  4. headers_send(103);
  6. // your slow algorithms and SQL queries 🤪
  8. echo <<<'HTML'
  9. <!DOCTYPE html>
  10. <title>Hello FrankenPHP</title>
  11. <link rel="stylesheet" href="style.css">
  12. HTML;

Early Hints are supported both by the normal and the worker modes.
