Completely agree with Larry here. spl_autoload_register is __autoload++.

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.
