PHP - Further Web Page and Network Handling

Further Web Page and Network Handling - PHP module H112

Applications often require a series of forms to be completed, with the final outcome being determined by the inputs from all the forms along the way. Furthermore, your web site may have several visitors filling in a series of forms at the same time. It's vital that you should be able to remember information from form to form, and also be able to tell your users apart from one another. This module covers the techniques used to "maintain state", and the PHP functions provided to help you do so.
