require_once 'Zend/Loader.php'; Zend_Loader::loadClass('MyClass');
require_once 'Zend/Loader/Autoloader.php'; $autoloader = Zend_Loader_Autoloader::getInstance(); $autoloader->registerNamespace('MyApp_');This example shows how to use the autoloader to load classes dynamically. The registerNamespace method is used to specify a namespace that will be used to autoload classes. In this case, it is 'MyApp_'. Both examples use the Zend Framework library, which is a package library for PHP. Zend Framework is a collection of packages that can be used to develop web applications. It includes packages for database connectivity, form creation, and more.
