DevShed has posted the second installment of their look at the Abstract Factory pattern in a new tutorial - "Creating AJAX Requester Objects with Abstract Factory Classes in PHP 5".

In this second article of the series, I'm going to demonstrate how to apply the abstract factory pattern to create diverse AJAX HTTP requester objects, which can be used in distinct contexts.

They work through Ajax development, creating the requestor objects for it, integrating it into the Abstract Factory pattern, and showing it in action - sending a simple message back to the calling script.
