Essentially, the autoloader knows where it is and should know where everything else it is expected to load is. Having a naming convention that say maps class name to file path/name (Zend_Soap_Wsdl_Exception maps to ./Zend/Soap/Wsdl/Exception.php) and sticking with it allows for a single autoloader to be used for any root name. Autoloading only really works out-the-box with classes. There has been discussion on making this work with functions and namespaces. -- ----- Richard Quadling "Standing on the shoulders of some very clever giants!"
