I've been researching Zend Framework lately and was curious about what's actually happening behind the scene of the whole dispatch process. Inspired by Thorsten Ruf's (zenddispatch_en.pdf) clear and beautifully presented workflow, I decided to go a step deeper and crawl Zend Framework's code. I came up with my own version of the flexible yet complicated workflow.

You can check out this new PDF here. It diagrams out an overall view of the request handling, a look at what happens inside the front controller including components like the Controller Dispatcher, Action Controller, Action Helper Broker and Response Object.

Apart from the new exciting features we have in symfony 1.1, this version also represents a year of hard work to refactor the internals. Let's dig into symfony internals a bit!

They talk about the new platform that everything is built of off now including the framework itself (complete with diagrams mapping out the different parts of the MVC whole).

So, as I've written in an earlier article on how to install FFMPEG on your server, while there are those who probably use a '�YouTube Clone'� script, there might be those who want to create their own using FFMPEG & PHP. FLV is the most widely used type of codec that runs on most Flash players.

The tutorial started with a diagram that outlines how the mini-app will work and is followed by the source. The script sets up the environment then grabs the file and sends it to the FFMPEG handler to be parsed and output as the FLV file (courtesy of a few handy command line parameters).

Zend Framework 0.6.0 release comes with improvements in Zend_Controller area (new Zend_Controller_Request, Zend_Controller_Response classes, dispatch process improvements), which looks very promising. Dispatching process now better described and its parts (Zend_Controller_Router and Zend_Controller_Dispatcher) are replaceable.

He also includes a diagram of how it's all laid out and a brief description of how each of these new pieces works.

Visustin is the ideal diagramming tool for software developers and document writers. Save your documentation efforts by automatic charting! Visustin reverse engineers your source code and visualizes it. No manual drawing is required. Your existing code is all you need. If you see a real complex case, print it out as a big mosaic and hang it on your wall.

Functionality includes the automatic creation of a optimized layout, the ability to do a multi-page printout, saving the graphs/charts/etc in various formats, run a "bulk chart" on all of your files at once, and export options including PowerPoint, out to the web, and Word.

You can get the full details on the product (as well as screenshots and a demo) from their website.
