In this article I describe how to use Zend framework components in a CakePHP application by means of building a very simple CakePHP application using Zend_Service_Flickr, a component for accessing the Flickr web services.

I was wondering about how to extend a singleton class such that you could retrieve the new class when retrieving the singleton later. In particular, Zend_Controller_Front is a singleton, but what if I want to extend it later? A number of plugins in the Zend Framework, particularly view helpers and routing functionality, make use of the singleton; would I need to alter all of these later so I could make use of the new subclass ?

Introduces a concept of reusable "generic" actions, which are controllers that you can easily reuse.

What do you guys think of Zend_Validate?
I haven't looked at Zend_Validate much, but I'm not really a fan of complex interfaces either. I like your idea to validate all that needs validated in one go, but I don't like your interface for adding validators.

The Zend Framework offers a pretty slick solution for accessing Amazon's Web Services. For this reason, I decided to adopt it for my project. Using its Amazon Service component in conjunction with a few others that are packaged with the framework, I created the application in almost no time at all. Here, my article recounts how I went about creating this application and shows you just how rapidly you can create applications using this wonderful solution.

Zend_Service_Audioscrobbler is a simple API for using the Audioscrobbler REST Web Service. The Audioscrobbler Web Service provides access to its database of Users, Artists, Albums, Tracks, Tags, Groups, and Forums. The methods of the Zend_Service_Audioscrobbler class begin with one of these terms. The syntax and namespaces of the Audioscrobbler Web Service are mirrored in Zend_Service_Audioscrobbler.

The Zend_InfoCard component implements relying-party support for Information Cards. Infomation Cards are used for identity management on the internet and authentication of users to web sites (called relying parties).

Detailed information about information cards and their importance to the internet identity metasystem can be found on the IdentityBlog

In this example, we write a configuration file. Then we read the configuration from the file. Or we extract configuration parameters. We use a PHP configuration file, an INI configuration file, or an XML configuration file.

After getting a little impatient looking at PHP code from however many projects and seeing the typical approach of making input filtering, sql and output escaping the responsibility of the human error-prone developer, I'm now making it standard practice on any of the projects I run to dump this sorry mess. And it is usually a mess.
The fact is you cannot trust a developer to manually secure source code - it's like God relaying the Ten Commandments to Moses. No matter how many burning bushes, prophets, unnatural disasters, signs and miracles you use to emphasis those ten simple rules, you can still wager there will be a bunch of folk breaking them (including myself!) left, right and centre. It's human nature to err. It's my nature to make the verb "err" redundant.
