PHP: Site registration and confirmation with a Validation code Image Support
In the second part of this series on building a registration and confirmation suite in PHP, Allan builds a testing script so that you can test the pages without being logged on or using a SMTP server, and builds a Validation Code Image display and checker, similar to the one illustrated, so that you can be sure that it's a real person registering, and not an automated script.
Please note that this article forms part of a chapter in the DMXzone e-book PHP Web Applications for Dreamweaver: Juicy Solutions for the Busy Developer.
Allan comes from Cape Town, South Africa. He has been implicated in writing for several WROX, glasshaus, Wiley and Apress publications, generally in the 'cool stuff that PHP can do' sections.
