[Returning] to the subject of this last tutorial, I'll introduce another method for enforcing object types in PHP 5: the "Type Hinting" feature. It can also be used in conjunction with the "instanceof" operator that you learned about before, in order to develop PHP applications that implement thorough routines for filtering unwanted objects. Generally speaking, when you finish reading this article, you should be armed with a few more methods for forcing object types in PHP, in this way expanding your overall knowledge of object-oriented programming.

They start with an introduction to type hinting and some basic examples of its use. From there, they build up a relevant example with the help of their (X)HTML widget class they've used throughout the series.

The first version of the user manual for eZ publish 3 is now available online. The manual is a non-technical guide for end-users of eZ publish.

Cache_lite is a php/pear caching module that is designed for high traffic sites. It is different than most caching systems because it has a built-in locking mechanism that will prevent cache corruption that can sometimes occur when there are a large amount of concurrent users trying to read and write to your cached data.

He wastes no time getting to the examples, showing first a very basic example of chacing/looking for a cache of your data. There's no installation HOWTO, but if you're familiar with the PEAR system, installation should be a simple matter.

Derick wrote an article about eZ components for the latest issue of php|architect. It deals with the goals for the project as well as architectural decisions that we took while developing this components library.

The new online user manuals for eZ publish are available online. They are part of the documentation and describe the administration interface as well as daily tasks.

In this month's issue of php|architect you can find an article on the eZ components. In this article I explain the goals for the project as well as architectural decisions that we took while developing this components library. It also shows a small example on how to use the components. Unfortunately the service (http://geo.derickrethans.nl.) it talks about is not yet life... I should get that going soon.
