Welcome to the conclusion of a five part series that shows you how to implement lazy and eager loading in PHP 5. These two design patterns allow you to handle the resources for an application in very different ways. Through numerous code examples, I've demonstrated when it is appropriate to use each method.

Welcome to the fourth chapter of this series on implementing lazy and eager loading in PHP 5. In five friendly tutorials, this series walks you through the basics of using these powerful approaches for including classes on request in your scripts, and teaches you how to work with these patterns when manipulating properties of a certain class.

Welcome to the third part of a six-part series on building persistent objects in PHP 5. Through a decent variety of code samples, this series provides you with the right pointers to start creating objects that can save themselves to a persistent storage mechanism, including simple cookies, plain text files, and MySQL database tables.

Despite its rather intimidating name, persistent objects represent a pretty simple concept applied very often in software development. It's aimed at creating structured entities that can maintain their status across different stages of an application. This six-part series will take the mystery out of persistent objects so you can use them in your own applications.

Welcome to the third part of a five-part series on lazy and eager loading in PHP 5. In this part of the series, you'll learn about the lazy design pattern, and how to use it effectively in your applications.

Welcome to the second installment of a series that shows you how to implement lazy and eager loading in PHP 5. Through a strong hands-on approach, this series teaches you how to use these patterns in some typical scenarios. In this way, you'll grasp their underlying logic and learn quickly how to take advantage of their functionality to speed up your own PHP-based programs.

The HTTP protocol is stateless, but sometimes it is necessary to make web applications store or remember information. This is sometimes referred to as persistent storage, and it takes on a number of different forms. This six-part series of articles will explain the concept and show you various ways to give your web applications a memory.

As you may know, design patterns are proven, well-trusted solutions that tackle a specific problem that occurs frequently in software development. As with many other principles and paradigms in this area, some patterns are more popular and easier to learn than others, and when applied properly, can considerably improve the efficiency and performance of an application. This five-part article series will discuss two of these.

Welcome to the final episode of a series that shows you how to use filters in PHP 5. Made up of nine parts, these articles show you how to utilize the numerous checking filters that come with the filter library. You can use them to thoroughly validate the incoming data handled by your PHP programs, without having to spend a long time coding custom functions or class methods.

Welcome to the conclusion of an eight-part series on building helpers in PHP 5. It's been a long journey, modifying our helper class to make it do what we want it to. Finally, in this last part, we'll put the finishing touches on our validation class so that it functions properly, without the need to spawn helper objects.

Welcome to the eighth part of a nine-part series on using filters in PHP 5. In this part, I discuss how to use the filter extension for sanitizing strings in all sorts of clever manners. I'll show you how to encode quotes, low and high ASCII characters in literals, and remove them in the same easy manner. Doing this can help prevent SQL injections and XSS attacks when developing PHP applications.

Welcome to fifth and final part of this series on creating a dynamic Twitter signature image in PHP. In the last segment, I showed you how to implement custom PHP exceptions as an error-handling mechanism in your signature image application. Today we’re going to wrap up our signature image application by adding a caching feature. This is a two-fold solution that both boosts performance and overcomes a pitfall in the Twitter API.

If you’re an enthusiastic PHP developer interested in learning how to build helper classes, you've come to the right place. This article series will teach you in a few simple steps how to build several kinds of helper classes for manipulating strings, generating dynamic URLs and validate incoming data, and so forth.

Welcome to part four of a five-part series on creating a dynamic Twitter signature image in PHP. In the last segment, I showed you how to implement PHP 5 exceptions as an error-handling mechanism in your signature image application. Today we’re going to expand upon that concept by creating a custom exception class for handling error states in our application.

If you’re a PHP developer who wishes to learn how to take advantage of the solid functionality provided by the filter extension that comes with PHP 5, then look no further, because you’ve come to the right place. Welcome to the seventh part of a nine-part series that gets you started using the most useful validation filters included with this PHP library.
