Throughout this chapter, 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.
