Um, the command line for starting the built-in webserver seems wrong. According to the documentation[1], test.php is used as router script, what is probably not intended. Just try to start the server without the script argument: php -S 127.0.0.1:8000 [1] <http://www.php.net/manual/en/features.commandline.webserver.php#example-383> -- Christoph M. Becker
