First, Zend_Controller_Action::_forward() is not a static method.
Second, make sure you understand its signature:
protected function _forward($action, $controller = null, $module = null,
array $params = array());
It works like this:
* If only an $action is provided, it forwards to that action in the
current controller and module
* If an $action and a $controller are provided, it forwards to that
action and controller in the current module
* If an $action, $controller, and $module are provided, it forwards
to that action and controller in the provided module.
* $params may be provided at any time (pass null to any unneeded
parameter), and will be used to set parameters in the request
object.

Use the response object's setBody() and appendBody() methods for
displaying content. So, instead of:
echo '<pre>', print_r($post, 1, '</pre>';
You'd use:
$this->_response->appendBody('<pre>' . print_r($post, 1) . '</pre>');
// or
$this->getResponse()->appendBody('<pre>' . print_r($post, 1) . '</pre>');
Then, if you want a particular action to always overwrite any previous
content, use setBody():
$this->_response->setBody('Thanks for verifying your identity');
You could also do this just before your call to _forward():
$this->_response->setBody('');
$this->_forward('index', 'verification');

Not much -- it's all being handled as PHP arrays; you're simply
unsetting previous values.
