PHP HELP, PHP TUTORIALS, OBJECT-ORIENTED PHP5 PROGRAMMING

Welcome to the second part of a seven-part series on the magic functions in PHP 5. In the previous article, we looked at property overloading with the get and set functions. In this one, we'll take a look at the same task using the isset and unset magic functions.

PHP form input validation is what separates amateur and professional PHP developers. A professional PHP developer validates data for both security and correctness of the data entered. Keep reading to learn how to validate user input to your forms.

When trying to maintain a secure protocol on an Apache-based website, you can expect to deal with certain issues, especially if you're also trying to rank well in the search engines. This article provides you with some solutions for two of the more difficult problems: duplicate content and 301 redirects.

Loading sources on the fly is one of the most common tasks that PHP programmers have to tackle during the development of web applications. This typical situation must be faced independently of the scale of the programs being created. This means a loader mechanism must be developed. Keep reading as we take a close look at these mechanisms in this eight-part article series.

It’s not breaking news that the release of PHP 5 drastically changed the way that many developers build their web-based programs. The incorporation of a much more robust object model, along with the introduction of native exceptions, type hinting and so forth (add your own improvement to the list) has given the language the maturity that we see in it today. This seven-part article series will explain an important new feature: magic functions.

If you use osCommerce for your site's e-commerce, and you're not happy with the quality or quantity of visitors your site receives, keep reading. Though osCommerce provides some excellent features, its weaknesses could be getting in the way of giving you the number of visitors and conversions you expect. Fortunately, there's a solution, hidden in something as simple as a title tag.

The link rel canonical tag lets you solve canonical issues for your URL without having to resort to 301 redirects or other potentially complicated approaches. This article explains how to take advantage of the tag in your PHP-powered web sites.

Sorting search results by post title in WordPress is often useful, if your website needs its entries to be sorted alphabetically. As a quick background, WordPress is the most popular open source, free blogging/CMS platform. However, the default search results are sorted by date, so there is no easy way to sort them alphabetically except to edit the core WordPress search functionally source code.

Welcome to the conclusion of a seven-part series on handling views with the Code Igniter PHP framework. If you're learning how to use the Model-View-Controller schema, this series of articles can help you get a better grasp of how to use it to quickly and dynamically generate web pages. In this part, we will finish building the database-driven application we discussed in the previous part.

PHP and MySQL form a powerful combination of open source technology available to any web developer. One of the increasing trends in modern web development is the generation of online contracts. E-commerce websites selling services online need automated contract generation for faster delivery of services. This article will help you learn to use this technology so you can get it working on your web site.

Welcome to the sixth installment of a seven-part series on handling views with the CodeIgniter PHP framework. This series shows you a few handy approaches that you can implement quickly within your CI-based programs to work with view files in a truly clever way, ranging from loading them sequentially to nesting views within other views.

Manipulating views with CodeIgniter is a straightforward process. In a typical situation, there’s a model that fetches some rows from one or more database tables, and a view file that receives this data through a controller class, which is finally displayed on screen, generally in the form of an HTML page. However, CodeIgniter gives PHP programmers enough freedom to handle views in several useful ways, which can speed up the development of web applications. Therefore, if you’re taking your first steps with CI and wish to learn some handy approaches that will help you work with views in a truly painless fashion, then start reading this tutorial now!

The active record pattern allows you to access records in a database by means of a unified interface, generally composed of a few data mapper objects. However, as with other popular design patterns, there are several methodologies for implementing it within an object-oriented application, all of which can be used to obtain similar results. In this group of articles, I demonstrate how to progressively build a MySQL abstraction class that uses the active record approach for performing CRUD operations (Create, Retrieve, Update, Delete) on the records of a selected database table.

When it comes to generating both static and dynamic web pages, CodeIgniter gives PHP developers the liberty of working with different approaches that can be easily adapted to suit the requirements of a huge variety of web applications. Building web pages using CI demands that you always deal with one or multiple views, generally represented in the form of HTML files that contain embedded PHP variables. Therefore, if you’re a CI user who want to learn to manipulate views in some clever ways, keep reading. In this series of articles, you’ll find a comprehensive guide to several methods you can implement within your own CI-based applications to handle view files in a truly efficient manner.

In this group of articles you’ll be provided with an approachable guide to building a database accessing class that will use the programming model imposed by the active record pattern for performing raw CRUD operations on a group of selected MySQL tables, and for fetching database records by using the WHERE, LIKE and LIMIT clauses as well. This is the sixth part of a seven-part series.
