And that's about all for the moment. In this article, you expanded your knowledge of PHP's OOP capabilities by actually using all that theory to build something useful - a form validation widget which can be used to verify the data entered into an online form, and provide a way for you to take action in case the data entered by the user does not met your expectations.
If you're a stressed-out Web developer working on a Web site, a Web application or an embedded system, you might find this object a handy tool in your next development effort. If you're a novice programmer struggling to understand how OOP can make your life easier, I hope this article offered some pointers, as well as some illustration of how object-oriented programming works. And if you don't fit into either of those categories - well, I hope you found it interesting and informative, anyway.
