In this fourth part of a 12-part series on method chaining, I start building a basic MySQL abstraction class that implements a few straightforward methods. Of course, the methods can be easily chained to each other, which permits us to build different parts of a SELECT statement through a truly compact and readable API.

In this third part of a 12-part series on method chaining, I complete the definition of the sample string processor class. This process will help reaffirm the concepts that you learned before regarding the definition and implementation of chainable methods in PHP 5.

Do you want to learn how to handle PHP WHILE loops? WHILE loops are one of the most powerful features as well as the easiest loop available to any PHP/MySQL developer. They enable us to shorten repetitive tasks for a highly useful application. This tutorial gives examples of WHILE loops in PHP/MySQL that beginner and novice developers can use as a quick reference for building similar loops in their applications.

In this second part of a 12-part series on method chaining, I explain how to extend the functionality of the string processor class by adding to it a few simple chainable methods. I conclude this part by defining a factory method within the string processor class.

Many sites feature web forms to collect information from users. Unfortunately, these forms often provide a poor experience for the user, with predictable results. This article will show you how to make filling out web forms more fun (or at least less painful) for your users with the help of PHP and some AJAX magic.

Method chaining is a useful technique that helps you to write more compact and powerful code. In this first part of a series that introduces you to this programming methodology, you'll learn how to define and use chainable methods in PHP 5. The process is quite simple to grasp, even if you have only an intermediate background in using the object-oriented paradigm.

Welcome to the sixth part of a series covering the dependency injection pattern. In this part, I build a PHP 5-based application that can work seamlessly with MySQL and SQLite. It will feature a simple interface and a MySQL driver.

In this fifth part of a six-part series on the dependency injection pattern, I explore the implementation of the pattern by using a simple setter method within a model class. You'll see that this approach is very easy to follow.

Welcome to the fourth part of a series on applying the dependency injection design pattern in PHP 5. Through a strong hands-on approach, this series teaches you several methodologies that you can use for taking advantage of the functionality given by this simple yet powerful design pattern. It shows you how to build classes that follow the schema imposed by the Inversion of Control software design principle.

In this third article of a six-part series, you will learn how to implement the dependency injection pattern by using a simple setter method. This process is very similar to the one that uses a constructor, which we covered in the previous article.

While not being as widely known as other design patterns such as Factory, Singleton or Active Record, the Dependency Injection pattern provides both programmers and web developers with a well-structured solution that allows them to solve issues that arise when an object needs the functionality of another one (hence the dependency) to work as expected. This is the second part of a six-part series that shows you how to apply this pattern.

In this first part of a six-part series, I introduce you to the dependency injection design pattern and its use with MySQL. Specifically, I create a typical scenario where one persistent class needs the functionality of its dependency, in this case a database handler, to gain access to a MySQL table.

Statistics aren't just for Excel spreadsheets anymore. If you've been wondering how to use PHP to help you do a basic statistical analysis, keep reading. In this article you'll learn how to use PHP to help you compare data sets.

Have you ever thought of doing statistical analysis using PHP? Well, as simple as this technology can be, it enables an analyst to do server-side scripting commands which accept data from a web form, and then analyze the data in the server using PHP.

In the first part, you learned about CSS and some basic tips/techniques for using the slider to display colors. In this part, we will discuss how we are going to write our AJAX and PHP scripts to make our user-defined CSS website.
