Hello World

PHP comes with a built in server that helps to speed up developing by not having to configure a system web server, first create file index.php;

        <?php
           echo "Hello World";

Now run the server;

        $ php -S localhost:8000

Open your browser and browse http://localhost:8000, you should see "Hello World".
