Robert Basic has a new post today about the autoloaders in Zend Framework 1.12 and how to use them to create a classmap for use in your application.

The latest, and last, release of the Zend Framework 1.x series is just around the corner as ZF 1.12.0RC1 was announced this week. As I still have projects running ZF1 I thought about giving the most interesting new feature (for me) a spin - the new autoloaders which are backported from ZF2. I decided using the classmap autoloader as the main autoloader, and the good ol' standard autoloader as the fallback autoloader.

He includes the changes to the Front Controller (index.php) to have it know about these new autoloaders and has a command that will go through your code any pull out any require_once statements out and let the autoloader handle it instead.
