Summary

If you've kept up so far, things should be getting exciting now. You have the tools to create truly sophisticated and interactive environments. There are still a few things 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 is the subject of the next hour.

Throughout this hour, you have learned how to work with the $GLOBALS associative array and acquire predefined variables, form input, and uploaded files using global variables. You have also learned how to send raw headers to the client to redirect a browser. You have learned how to acquire list information from form submissions and how to pass information from script call to script call using hidden fields.
