PHPImpact Blog:
Analysis of coupling within the Zend Framework
Jun 09, 2008 @ 07:56:00

As the PHP:Impact blog points out there's a new post from Neil Garb talking about the (loose) coupling going on inside the Zend Framework.

One of the Zend Framework's strongest drawing cards, as I see it, is its loosely-coupled structure. The name Zend Framework may be a misnomer, in fact, as ZF is more a set of reusable libraries than an actual application framework. I won't go into detail about the advantages of loose coupling, but a recent discussion on the ZF mailing list prompted me to investigate just how loosely coupled the framework is.

He's created a few graphs to show the extent of the coupling - a directed graph, the density of it and example code showing deep and shallow coupling. Here's his results.
