Things are really getting exciting now! You have the tools to create truly sophisticated and interactive environments. A few things are still missing, of course. Now that you can get information from the user, it would be nice to be able to do something with it. Write it to a file, perhaps. That's the subject of the next hour.
Throughout this hour, you learned how to work with various superglobals and form input. You also learned how to send raw headers to the client to redirect a browser. You learned how to acquire list information from form submissions and how to pass information from script call to script call using hidden fields. Finally, you learned how to send your form results in email, and also how to upload files through your Web browser via a PHP script.
