1.initialize
$viewConfig=array();
$viewConfig['scriptPath']=$config->getSetting('framework','view_dir');
$view=newTravello_View_Smarty($viewConfig);
Zend::register('view',$view);

2.Withinyourcontrolleranactionmethodcouldlooklikethis.

publicfunctionindexAction()
{
$temp_file='homepage.htm';

$view=Zend::registry('view');

if(false===$view->isCached($temp_file))
{
$vars=array();
$vars['title']='Page<title>';
$vars['text']='Atextisatext&atextisatext.';
$vars['numbers'][0]=12.9;
$vars['numbers'][1]=29;
$vars['numbers'][2]=78;

$vars=$view->escape($vars);

$view->assign($vars);
}

$view->output($temp_file);
