There is no 'Zend' class in current distributions of ZF.
That said, several ZF classes have an init() method that they call from
the constructor. The reason behind this is that some of the abstract
classes have very specific constructor signatures, and to simplify
extending them they call an init() method at the end where developers
may add additional initialization functionality.
As an example, here's the constructor signature for
Zend_Controller_Action:
public function __construct(
Zend_Controller_Request_Abstract $request,
Zend_Controller_Response_Abstract $response,
array $invokeVars = array())
Who would want to write that every time they wanted to add
initialization-time logic for their controllers?
So, init() isn't a PHP method, but is instead a convenience method we've
added to a number of ZF classes. In all cases I know of, it's called as
the last action in the constructor, so it's effectively an instantiation
method.
