The Pragmatic Programmer is written as 46 small sections, each section ranging from two to ten pages long. Sprinkled through these sections there are 70 tips: one-line statements of best practice that the authors try to live by daily. Addison Wesley has kindly allowed them to make available some sections from the book and a complete, annotated list of tips. Also included here are many excellent articles explaning and detailing the process of software development.

Extracts from the books, The Pragmatic Programmer:

• The preface, just to give you an idea of what we're trying to do in the book.
• What triggers the decay of perfectly good software? We discuss what we believe is the major cause in Software Entropy.
• Are your programs relying on luck to work? Sometimes you might be surprised. Read about programming deliberately and Programming by Coincidence.
• In Evil Wizards, we discuss the problems inherent in relying on the code produced by wizards (such as those found in most moderns IDEs).
• In a world of increasingly complex code, resource management is crucial. Yet still our programs leak memory, leave files open, and generally fail to tidy up after themselves. Balance Resources looks at some simple techniques which will make our programs better citizens.

70 Programming Tips from the book, The Pragmatic Programmer

Articles and Presentations from the authors of the book, The Pragmatic Programmer, here are some of these:

• Practice (pdf)

PHP is an open-source, reflective programming language. Originally designed as a high-level tool for producing dynamic web content, PHP is used mainly in server-side applications. PHP 5 is the latest version and includes new features such as PHP Data Objects and more performance enhancements. PHP generally runs on a web server, using PHP code as its input and creating Web pages as output. PHP can be viewed as an alternative to Microsoft's ASP.NET/C#/VB.NET system, Macromedia's ColdFusion, Sun Microsystems' JSP, Zope, mod_perl and the Ruby on Rails framework.
 
The LAMP architecture has become popular in the Web industry as a way of deploying inexpensive, reliable, scalable, secure web applications. PHP is commonly used as the P in this bundle alongside Linux, Apache and MySQL. PHP can be used with a large number of relational database management systems, runs on all of the most popular web servers and is available for many different operating systems. This flexibility means that PHP has a wide installation base across the Internet; PHP is one of the most popular programming languages for implementing websites with over 20 million Internet domains using PHP.

PHP Patterns: The Observer Pattern Continued Continued from part 1 of PHP Patterns: The Observer Pattern

PHP Patterns: The Observer pattern The Observer pattern is perhaps most often encountered in traditional graphical user interface desktop applications. It is an excellent way of ensuring that disparate display components reflect changes at a system's core. As we shall see, though, it remains a powerful technique in a Web-oriented environment.

PHP Patterns: Introduction Even if you have never set eyes on a pattern catalog in your life, you have probably come across the phrase design patterns in recent years. You may even have assumed that patterns were yet another fad. After the turn of the century it suddenly seemed that patterns were everywhere, and PHP was not immune.

Implementing MVC in PHP: The Controller Quite simply, the controller handles incoming requests. It uses input, in this case from the URI, to load a module and refresh/render the presentation layer. The controller for the aptly named Framework 1.0 uses a few GET arguments to figure out which module to load.

Using Objects to Create an Application This tutorial is the second in a series dealing with using objects to create an application -- building the application up from smaller parts -- and teaching important software engineering and design concepts that will be useful writing not only in PHP, but in other languages as well.

The MVC pattern  The MVC pattern very commonly used in constructing web applications. The principle allows us to construct 3-tier applications, allowing us useful layers of seperation in our code, and helping both designers and developers to cooperate as well enhancing our ability to maintain and expand on existing applications.

Why PHP 5 Rocks! The title really says it all!

Easy unit testing in PHP Unit tests are one of the greatest advances in programming since object orientation. They allow for a safe developement process, refactoring without fear, and can sometimes replace documentation since it explains quite clearly what an application is supposed to do. This tutorials contains an overview of the available Unit Testing tools for PHP applications and explains how to use them.
