  Implementing the Data Mapper Design Pattern in PHP 5

  Posted: March 10th, 2010, 7:00am MST

  In this first part of a five-part series, I introduce you to implementing the Data Mapper design pattern in PHP 5. This pattern attempts to solve the issue of the strong coupling that often exists between the domain objects present in an application and the underlying persistence mechanism. This benefit comes at a cost, since data mappers add a new layer of complexity. Living with this minor trade-off is quite worthwhile, though, as you'll see.
  - Since the web is in constant evolution and merges a variety of technologies and languages, developing web applications (specially mid-sized and large-scale ones) has become a challenging process. Indeed, applications require extensive planning, modeling and testing, before reaching a stable depl...

  Defining an Abstract Class with Restrictive Constructors in PHP 5

  Posted: March 9th, 2010, 7:00am MST

  In this second part of a four-part series, I rebuild the example application developed in the previous tutorial. As you'll recall, it used a protected constructor to prevent the instantiation of the base array iterator class. In this case, a better result will be achieved by declaring the iterator abstract; still, the example demonstrates a simple utilization of a restrictive constructor in a concrete situation.
  - Unquestionably, the introduction of a more robust object model in PHP 5 has provided developers with additional features that allow them to build efficient and thorough object-oriented applications without the need to appeal to the ugly programming hacks used frequently in the bad old days of PHP ...

  Working in the Method Scope with Static Variables in PHP 5 Classes

  Despite their name, static properties can help in a wide variety of situations. If you're not using them currently, and you regularly implement design patterns in your code, after reading this series you'll wonder how you ever did without them. This article is the conclusion to a four-part series.
  - The term static is misleading when applied to a property of a class in PHP 5. It may lead you to think that a property like this does nothing particularly useful, or simply that its functionality is so irrelevant that it can't be considered a truly dynamic in-memory place. Fortunately, this ini...

  - While at a glance the subject may seem rather irrelevant and even pretty boring, the truth is that the proper use of static variables in PHP 5 classes can be of great help in improving the way that they perform certain tasks and their relationship in a given application context.

This functional example shows that the use of a simple static property makes it easier to implement the Singleton pattern, which is convenient when developing a class that abstracts the access to a database server, be it MySQL or a different one.
  - Understanding the behavior of static class properties in PHP 5 is a straightforward process that can be tackled with minor headaches, even for inexperienced developers taking their first steps into the huge and sometimes esoteric field of object-oriented programming.

  Understanding TCP/IP Protocol Types

This applies to the world of computing as well, where the set of standards are called protocols. During this article we plan to present in a nutshell the most common TCP/IP protocol types. We wont get in-depth, so dont expect university course-style material just the basics.
  - Before we move on, let's fully grasp the concept of protocol and explain how more of those build up a structure called the OSI model. How are they important to us? Finally, we'll get into enumerating the popular TCP/IP protocols. These are the ones we need to be familiar with, since our applications...

  Implementing Factory Methods in PHP 5

  Posted: November 24th, 2009, 7:00am MST

  If youve ever developed desktop applications using mature object-oriented languages like C++ and Java, then its possible that youve found yourself saying a few funny phrases such as “I need to implement a factory method within this class,” or in the worst case: “this class needs to implement a factory method, but I dont have a single clue about how to do that.” Surprisingly, you can implement these factory methods pretty quickly and easily in PHP 5, as this six-part series will show you.
  - To be honest, I grappled with factory methods in Java myself, but in the end I learned not only how to quickly build factory methods in Java classes, but how to implement those methods in PHP as well. While it's undeniable that PHP is easier to learn than Java, many PHP developers with long e...

  How to Split a File During an FTP Upload Using PHP

  Posted: November 17th, 2009, 7:00am MST

  One of the known limitations of free hosting packages is the file upload limit. For example, some hosting companies set an upload limit of 500 KB. This means that for any uploads to the FTP server, the file should not be more than 500 KB or else the server wont accept it and you will not be able to upload your file. Fortunately, by splitting your files, you can get around this limitation; this two-part tutorial series will show you how.
  - Of course, some files that are important for web site functionality exceed 500 KB. For example, if you are running a web application that needs a geo IP database, a typical file for the geo IP DAT file is around 1.1MB. So this cannot be uploaded as one batch because it exceeds the upload limit of ...
