PHP HELP, PHP TUTORIALS, OBJECT-ORIENTED PHP5 PROGRAMMING

You've probably built custom functions and libraries to validate user input in PHP 5. There's an easier way to do this, and it can save you considerable time and effort. It involves using PHP 5's own built-in and often-neglected filters. This nine-part series will introduce you to their use.

Welcome to the final part of an eight-part series on building loader applications in PHP. In this part, we'll improve on the loader class we developed in the previous part by using certain specific functions from the Standard PHP Library (SPL).

Welcome to the seventh installment of an eight-part series on building loader applications in PHP. In this part, you will learn how to use the “spl_autoload(),” “spl_register()” and “spl_register()” functions to build a small file loader class. This class will be able to perform recursive searches through the file system to find a targeted resource.

Welcome to the fifth part of an eight-part article series that teaches you how to build loader applications with PHP. In this installment of the series, I explain how to create a small, efficient file loader class, with a difference: no instance of it needs to be spawned to include a targeted file, thanks to the implementation of a static recursive loading method.

Welcome to the sixth part of an eight-part series that shows you how to build file loader applications in PHP. In this part I will discuss how to build a helpful file loading application by taking advantage of the nifty “__autoload()” magic function.

Welcome to the sixth part of a seven-part series that shows you how to use the magic functions that come with PHP 5. In this article, I cover the “__destruct()” method, also known as a destructor. They can be really useful for performing all sorts of clean-up tasks, or for creating objects that are capable of maintaining their state across several HTTP requests.

Among the improvements and new features that were introduced to PHP 5, there’s a set of special functions, popularly known as magic functions. These allow you to perform all sorts of smart tasks, ranging from overloading properties and methods in classes, to using destructors and triggering automatically predefined processes when serializing and unserializing objects. This is the conclusion to a seven-part series that shows you how to use the magic functions in PHP 5.

Welcome to the third part of an eight-part series on building loader applications in PHP. In the tutorials that comprise this series you’ll find numerous examples aimed at demonstrating how to create small, yet efficient, resource loader classes, not only by taking advantage of PHP includes, but the handy “__autoload()” magic function and the Standard PHP Library (SPL) as well.

Magic functions are an important part of the numerous improvements and additions that were introduced originally in PHP 5. They can be extremely handy when it comes to simplifying the execution of complex tasks. This is the fourth part of a seven-part series that showcases some of the more useful magic functions and how to implement them.

If you’re an eager PHP developer who wants to have at your disposal a quick guide that shows you how to work with the most relevant magic functions provided by PHP 5, then this series of articles might be what you’re looking for. In this fifth part of a seven-part tutorial on magic functions, we'll briefly review the sleep and wakeup functions, and then tackle the clone function.

eWeek recently wrote an article that showed the top 10 programming languages developers should consider focusing on over the next few years. According to Deborah Rothberg, by learning these programming languages, you can not only keep but advance your career.

Welcome to the fourth chapter of the series that shows you how to build loader applications with PHP. Made up of seven parts, this series uses a variety of code samples to teach you how to create modular programs. These programs are capable of recursively including files required by a given application, without having to explicitly call any “include()/include_once()” or “require()/require_once()” PHP function.

If you’re a PHP developer who wishes to learn how to implement and use the set of magic functions that come included with PHP 5, you’ve come to the right place. Welcome to the third part of a series that takes a close look at magic functions in PHP 5. Made up of seven tutorials, this series teaches you how to work with the most common PHP 5 magic functions, putting particular emphasis on their usage within the context of object-oriented applications.

Spam is one of the biggest problems on the Internet. It is getting harder to fight with the advent of spam bots that visit websites and automatically fetch email addresses, fill out forms and do other nasty things, such as blog spam comments, that could degrade your integrity. Fortunately, using captcha can help. This article will show you how to implement captcha on your site.

If you’re a PHP developer who has already worked with popular third-party frameworks like Kohana and CodeIgniter, or even better, have created one all by yourself, then you're familiar with building file loading applications. The process can be tackled pretty easily, either by using a procedural approach or the object-oriented paradigm. In this eight-part series, we take a close look at building file-loading applications. This second part of the series will focus on static methods.
