Smarty and Zend_View integrantion

聚合使用 smarty

<?php
require_once ('Zend/View/Abstract.php');
class SmartyView extends Zend_View_Abstract
{
protected $_smarty;

public function __construct($config = array())

初始化脚本中设置 view

//Create the view and set the compile dir to template_c
$view = new SmartyView(array(
'compileDir' => './template_c'
));

//Create a new ViewRenderer helper and assign our newly
//created SmartyView object as the view instance
$viewHelper = new Zend_Controller_Action_Helper_ViewRenderer($view);
$viewHelper->setViewSuffix('tpl');

//Save the helper to the HelperBroker
Zend_Controller_Action_HelperBroker::addHelper($viewHelper);
