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