With bots getting intelligent enough to read easy versions of captcha, it's time to make your site a little trickier if you want to avoid spam. This article will show you how to set up a PHP web form with AJAX that uses Recaptcha, a more difficult protocol for bots to decipher.

One of the most important features in a website is the ability to show videos to your visitors. There are a lot of video hosting solutions nowadays, with YouTube as the most popular. However, due to its popularity, there are lots of services -- even free services -- that let viewers download your video files after you've uploaded them to YouTube. If you need to restrict downloading of your files, keep reading.

Welcome to the conclusion of a three-part series that shows you how to count the back links to your web site from unique domains using the Yahoo Inbound Links API. In the second part you learned how to pass the form variables to PHP using AJAX, process the web form input using PHP, and finally validate the root domain name URL using PHP. In this part, we discuss the details of the Yahoo API PHP script process.

In the first part of this three-part series, you learned the guiding concepts and design for building a PHP web application to count back links from unique domains using the Yahoo Site Explorer API. In this part, we will illustrate, in detail, how to do the programming for the PHP Ajax web form and the validation script.

If you've just started using the Yahoo Site Explorer Inbound Links API and want to know how far you can take it, keep reading. This three-part series will show you how to build an application that can help you track your links.

Welcome to the final part of a seven part series on building polymorphs in PHP. In a friendly fashion, this series gets you started constructing polymorph classes specifically in PHP 5. It shows you how to accomplish this by using first interfaces, then parent classes, and finally a proper combination of both.

In this penultimate part of a seven-part series on building polymorphs in PHP 5, I demonstrate how easy it is to build polymorph objects that merge the functionality of abstract classes and the structure of interfaces. The entire creation process is simple enough that you shouldn’t have major problems grasping its underlying logic.

In this fifth part of a seven-part series on building polymorphs in PHP 5, you will learn how to build a polymorph object by combining an abstract class and a simple interface. As you'll see, this object will be used for constructing basic HTML divs.

Welcome to the fourth installment of an article series on building polymorphs in PHP. Made up of seven tutorials, this series attempts to teach you through numerous, comprehensive code samples how to create polymorph objects. You'll see how to do it using interfaces, then abstract classes, and finally a combination of both.

In this third part of a seven-part series, I demonstrate how to build polymorph objects using abstract classes in PHP 5. As you'll see, it's a pretty straightforward process that can be tackled with relative ease.

In this second article in a seven-part series on building polymorphs in PHP 5, I provide you with another example of how to do this by way of a simple interface. For this tutorial, I decided to work with objects that are responsible for rendering different HTML elements, such as div and paragraphs, but naturally it’s possible to construct these types of object for different purposes as well.

You don't need to be working in a strictly-typed language like C to enjoy the benefits of polymorphism. You just need to achieve it at a different level. In this seven-part series, you'll learn how to use polymorphism in PHP 5.

In this second part of a two-part series on error and exception handling in PHP, we focus specifically on handling exceptions. This article is excerpted from chapter 8 of the book Beginning PHP and Oracle: From Novice to Professional, written by W. Jason Gilmore and Bob Bryla (Apress; ISBN: 1590597702).

Mistakes are inevitable, in life, programming, and application submissions. You can prepare for errors by making sure your application is designed to respond to them. This two-part article explains how PHP handles errors. It is excerpted from chapter 8 of the book Beginning PHP and Oracle: From Novice to Professional, written by W. Jason Gilmore and Bob Bryla (Apress; ISBN: 1590597702).

Despite their name, static properties can help in a wide variety of situations. If you're not using them currently, and you regularly implement design patterns in your code, after reading this series you'll wonder how you ever did without them. This article is the conclusion to a four-part series.
