The Zend Developer Zone has posted part four of their Ajax Chat Tutorial series (part 1, part 2, part 3) today focusing on enhancing the structure they've already created.

In part 4 of this tutorial we take a look at adding a new MessageAction method to our current Controller. This will expect one piece of information: a new chat message.

Of course, plenty of code is included and they show how to work with JSON messages over XML for simplicity's sake (via an updated IndexController).

Nefarious Designs continues their object-oriented PHP series with part four posted today, a look at some of the new features that PHP5 brings to the table.

After a welcome break, over the late summer public holiday here in England, here's the final part in my object-oriented PHP series. Sorry about the rather extended pause since "Part 3: Taking Relationships Further".

Having already looked at definition, relationships and taking those relationships further, I'm going to look at how PHP5's new Object Model introduces more advanced functionality.

In this latest part they look at clas constants, abstract classes, object interfaces, and magic methods (including overloading).

The IBM developerWorks site has posted part four of their series looking at the Zend Framework. This latest article focuses on the Zend_HTTP_Client package.

Part 3 explains how to use the Zend Framework to construct our online feed reader, Chomp, by creating an interface to subscribe to and read feeds, and to save feed entries into the database. Now you will learn how to use the Zend Framework to incorporate Web sites that do not support RSS feeds into the online feed-reader interface.

They work their way through an example of pulling in content from a remote site (one that's feedless). This is an enhancement to the "Chomp" application they've been developing all along, so if you need to catch up, here's the previous parts - Part 1, Part 2, Part 3.

They update the indexController, deleteEntryAction, and the saveEntryAction methods to handle this new incoming data and make the needed changes to the views to handle the new output. Finally, they demonstrate how to save the entries pulled in through the Zend_HTTP_Client component.
