  4. * Router script for the built-in PHP web server.
  5. *
  6. * The built-in web server should only be used for development and testing as it
  7. * has a number of limitations that makes running Drupal on it highly insecure
  8. * and somewhat limited.
  9. *
  10. * Note that:
  11. * - The server is single-threaded, any requests made during the execution of
  12. * the main request will hang until the main request has been completed.
  13. * - The web server does not enforce any of the settings in .htaccess in
  14. * particular a remote user will be able to download files that normally would
  15. * be protected from direct access such as .module files.
  16. *
  17. * The router script is needed to work around a bug in PHP, see
  18. * https://bugs.php.net/bug.php?id=61286.
  19. *
  20. * Usage:
  21. * php -S localhost:8888 .ht.router.php
  22. *
  23. * @see http://php.net/manual/en/features.commandline.webserver.php
