How to get getRequestUri() in layout.phtml - html

Question

In my zend layout.phtml I am serving my navigation like this:
<?php
$userInfo = new Zend_Session_Namespace('userInfo');
if($userInfo->userType=='admin')
{
echo '<li >home</li>';
echo '<li >Addbooks</li>';
echo '<li class="selected">EditBook</li>';
echo '<li>Adduser</li>';
echo '<li>Logout</li>';
}
?>
in a normal page I can get url this way
$this->view->assign('url',$this->getRequest()->getRequestUri());
$url = $this->getRequest()->getRequestUri();
$b=basename($url);
$this->view->assign('b',$b);
I want this url in my layout.phtm how can I pass this from bootstrap.php to layout.phtml? here my requirement is to add a class to li like this:
<li <?php if($b==EditBook) echo 'class="selected' ?> ">EditBook</li>

Better way to obtain it, is to write a view helper that will assign necessary variables
class Helper_Params extends Zend_Controller_Action_Helper_Abstract {
$view = $this->getActionController()->view;
$request = $this->getRequest();
$view->requestUri = $request->getRequestUri();
}
and init it in your Bootstrap
public function _initHelpers() {
Zend_Controller_Action_HelperBroker::addHelper ( new Helper_Params () );
}
