This blog was built with the Zend Framework. Getting it up and running so quickly was only possible thanks to Ralf Eggert's tutorial. In his blog, Ralf Eggert has described the framework's components very nicely.
I was able to use some of his suggestions in my blog. So once again: "Thank you."
Every PHP developer who wants to use ZF should read the tutorial at http://www.ralfeggert.de/
It analyzes every part of ZF in detail, step by step, and then shows where in an application the components can be used.
