Epguides.com Zend Framework API
Lately I have been writing Service API’s for Zext, my Zend Framework library extension. I plan on publishing some of the more useful ones over the next couple of months on my blog. The first of the series is the Epguides.com API.
Building a PHP Publish / Subscribe System
First post in a while. I have been busy working on some large application and finishing up my Computing Science Degree. Now that the piece of paper is safely secured above my fireplace, I’ve been trying to find time to do a new post.
I have been building a large application and one of the requirements is to trigger a certain action when an event happens. For example, trigger the sending of an alert email when a database row is updated. Some programmers may be tempted to simply hard-code this functionality into the model class, however this doesn’t give very strict class encapsulation, and can quickly become un-maintainable.
I use the Dojo Javscript toolkit for most of my dynamic front-end functionality. It has implemented a publish/subscribe system using dojo.publish() and dojo.subscribe(). This article will describe the implementation of a similar system using PHP. Read the rest of this entry »

Zend JSON-RPC with Dojo Howto
I have been using the Dojo toolkit as my Javascript library of choice since back in early 2006 when it was still around version 0.4. Since then, the project has made tremendous strides including the release of version 1.0 and 1.1 with 1.2 on the way. At the beginning of 2008 I started using the Zend Framework to build MVC PHP applications and, with the release of 1.5, it has become my PHP framework of choice.
To my delight, the Zend Framework and Dojo have recently announced a partnership which will lead to tighter integration of these two great open source frameworks.
One of the most exciting additions to the Zend Framework is the Zend_Json_Server support for JSON-RPC. I have been using JSON-RPC with Dojo for quite some time and, up until now, it has been challenging to find a design pattern that plays nice with the Model View Controller implementation in the Zend Framework. However, with the addition of the Zend_Json_Server this is no longer the case. Read the rest of this entry »
