Week 7 - Browser- Server interaction with PHP

The slides for this lecture describe how to use forms and sticky forms with PHP. Here are the full set of examples.

This approach is usable but depreciated ( i.e. you are advised not to use it). Most (All?) commercial hosting sites will require the more wordy but more secure approach.

I have also adapted a tutorial from the WebMonkey site and added some advice on how to use PHP at home, paying special attention to how to secure your server which is very important.
