PHP HELP, PHP TUTORIALS, OBJECT-ORIENTED PHP5 PROGRAMMING

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.

PHP as a server side scripting language can be used to customize CSS. This can make your website more readable and useful to your visitors. In this article, you'll learn what you can do to let them adjust your site so it looks good to them. This is the first part of a two-part series.

If you’re a PHP developer who wants to learn how to create objects that can maintain their state through different HTTP requests, either by using cookies, plain text files or MySQL database tables, then don’t look any further because you’ve come to the right place. Welcome to the last part of a six-part series on building persistent objects in PHP 5. This tutorial series introduces the key concepts that surround the creation of persistent objects, and complements the corresponding theory with copious code samples.

Welcome to the fifth part of a six-part series that shows you how to build persistent objects in PHP 5. In this part of the series, I'll show you how to develop a persistent class that can save its properties to a MySQL table.

Persistent objects appear at first to be an obscure and hard-to-grasp subject that belongs under software development. In fact, persistent objects are simply regular objects spawned from a class that has some form of storage mechanism associated with it. This six-part series shows you how to get the most out of persistent objects in your web applications.
