Creating a Module and Controller
$ zf create module admin
$ zf create controller index 1 admin
Note: Trying to create a controller that already exists in another
Module might result in an error. Depending on the Zend_Tool
Verion you have. The solution is to apply the patch from
ZF Issue Tracker: http://framework.zend.com/issues/browse/ZF-6853
Note: If you applied this patch, make sure all controller names in the admin
module start with Admin_

Registering the Module
class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
protected function _initAutoloadModuleAdmin()
{
$autoloader = new Zend_Application_Module_Autoloader(array(
'namespace' => 'Admin',
'basePath' => APPLICATION_PATH.'/modules/admin',
));
return $autoloader;
}
}
The method is called automatically by Zend_Application as it starts with _init.
You can choose the remainder of the method name as you like.
