Common misconceptions in web application development

CSS • Javascript • PHP • UI • Web development July 20th, 2008

Over the time I have developed for the web, I have read and heard many assumptions about development practices and technologies. This is my list of common misconceptions in (web) development:

1. OO code is less performant than procedural code

The number one argument against OO application design from procedural advocates. This argument is based more on intuition than fact. The usual examples pit short procedural code against equivalent OO code in which procedural code comes out triumphant as more terse and performant.

Handling mail and mime in PHP using the Zend Framework

Open Source • PHP • Web development • Zend Framework July 18th, 2008

Comet declares a reversal of roles, in which the server can notify the client whenever new data is available. This technique is very useful in a constantly changing environment such as stock prices or online messaging (chat).

The Advancing PHP Developer Part 5: Design Patterns

Javascript • PHP • UI • Web development July 12th, 2008

5. Design Patterns

A design pattern is a general reusable solution to a recurring design problem in object-oriented systems. Design patterns are essentially blueprints that suggest how to solve a particular set of OO design problems while adhering to OO best good-practices (which I've recounted in my Object Oriented part of this series).

To explain by example, lets have a look at the Model-View-Controller pattern, a common pattern in use on the web and a source of much confusion amongst aspiring developers. The Model-View-Controller pattern (abbr. MVC) is a general solution for decoupling domain logic from the user interface, resulting in much better maintainability for both.
